| CVE-2026-89949 | 1 Linux | 1 Linux Kernel | 2026-09-18 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: batman-adv: dat: avoid unaligned fault in IP extraction Independent of the alignment of the ARP packet in the SKB, either the batadv_arp_ip_src or the batadv_arp_ip_dst will have an unaligned access (on HW without native unaligned read support). Use get_unaligned() to handle this properly on all architectures. | ||||
| CVE-2026-89951 | 1 Linux | 1 Linux Kernel | 2026-09-18 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: batman-adv: fix stale receive device on merged fragments Fragment reassembly reuses the skb from the highest-numbered buffered fragment as the merged packet. When that fragment was received on a hard interface which is deleted before the chain completes, the merged skb can re-enter the receive path with a stale skb->dev and skb_iif. batadv_batman_skb_recv() passes such merged packets through the normal receive handlers again. DAT and bridge loop avoidance both derive the ARP header length from skb->dev, so they can dereference the freed net_device before the packet reaches the local mesh interface. Refresh the receive device metadata from the current receive device before running the packet handlers. This keeps internally reinjected merged fragments consistent with the normal receive path after hard interface teardown. | ||||
| CVE-2026-90002 | 1 Linux | 1 Linux Kernel | 2026-09-18 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: ftrace: Take trace_array reference before accessing its ftrace_ops The trace instance files set_ftrace_filter and set_ftrace_notrace was updated to work with specific trace instances (trace_arrays). The issue is that when these files are opened, there is a small race window where it will use the ftrace_ops from the inode->private pointer to get a reference to the trace_array and then take its reference. The problem is that the ftrace_ops itself could be freed. If the rmdir on the instance happens at the same time the set_ftrace_filter file is opened, the rmdir could have also freed the ftrace_ops and referencing it will cause a use-after-free bug and crash the kernel. Instead, pass in the trace_array as the file private data (NULL for the top level instance), and then pass both the trace_array and the ftrace_ops to the ftrace_regex_open() function. If the trace_array is NULL, then it just uses the ftrace_ops without the need to take its reference (like normal). If the ftrace_ops is NULL, that is only the case for the top level instance and the global_ops can be used. This allows the trace_array to have its reference incremented before touching the ftrace_ops that could also be freed when the instance is. | ||||
| CVE-2026-90003 | 1 Linux | 1 Linux Kernel | 2026-09-18 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: futex: Prevent rcuwait use-after-free during requeue PI On PREEMPT_RT, FUTEX_CMP_REQUEUE_PI can trigger a KASAN report (slab-out-of-bounds) in futex_requeue_pi_complete() invocation of rcuwait_wake_up(). The futex_q used by futex_wait_requeue_pi() is allocated on the waiter's stack. An early wakeup can race with a PI requeue as follows: waiter requeue task ------ ------------ futex_wait_requeue_pi() futex_do_wait() schedule() futex_requeue futex_proxy_trylock_atomic() futex_requeue_pi_prepare() Q_REQUEUE_PI_NONE -> Q_REQUEUE_PI_IN_PROGRESS * timeout/ signal wakes waiter * futex_requeue_pi_wakeup_sync() Q_REQUEUE_PI_IN_PROGRESS -> Q_REQUEUE_PI_WAIT requeue_pi_wake_futex futex_requeue_pi_complete() cmpxchg Q_REQUEUE_PI_WAIT -> Q_REQUEUE_PI_LOCKED rcuwait_wait_event() if (atomic_read(&q->requeue_state) != Q_REQUEUE_PI_WAIT) break /* no schedule() */ /* q.pi_state->owner == current */ futex_private_hash_put() /* return from syscall */ rcuwait_wake_up(&q->requeue_wait) /* q is gone */ futex_requeue_pi_complete() publishes Q_REQUEUE_PI_LOCKED before calling rcuwait_wake_up(). The waiter observes this state in rcuwait_wait_event() before invoking schedule() in rcuwait_wait_event(). Here, the waiter is free leave the syscall before requeue task can complete the wake. To address this race skip rcuwait_wake_up() in the Q_REQUEUE_PI_LOCKED case. This state is only published by requeue_pi_wake_futex(), which saves q->task before futex_requeue_pi_complete() and wakes the waiter via wake_up_state(). This wake is intended to wake the waiter from its futex_do_wait() sleep. If the waiter is still sleeping there, it can not get into the Q_REQUEUE_PI_WAIT state (and require this removed wake). Should the waiter be woken up from futex_do_wait() by other means (as in this example) and sleep in futex_requeue_pi_wakeup_sync() then the wake_up_state() from requeue_pi_wake_futex() will wake it, too. Should the waiter task terminate before wake_up_state() had a chance to wake the task then the task pointer does not become invalid because the futex_hash_bucket::lock is held and the task pointer is RCU protected.

| CVE-2026-90009 | 1 Linux | 1 Linux Kernel | 2026-09-18 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: scsi: bsg: Fix TOCTOU in io_uring passthrough command setup scsi_bsg_uring_cmd() reads bsg_uring_cmd from the shared mmap'd SQE. Userspace can change a field after we check it and before we use it. request_len is the sharp case: it can grow past sizeof(scmd->cmnd) after the bound check and overflow scmd->cmnd in copy_from_user(). READ_ONCE() the SQE fields we check or use into locals before use. | ||||
| CVE-2026-90011 | 1 Linux | 1 Linux Kernel | 2026-09-18 | 9.1 Critical |
| In the Linux kernel, the following vulnerability has been resolved: scsi: target: iscsi: Reserve a terminator byte for the login payload iscsi_target_check_login_request() rejects a login PDU whose DataSegmentLength exceeds MAX_KEY_VALUE_PAIRS, but the test is '>' and login->req_buf is allocated with exactly MAX_KEY_VALUE_PAIRS bytes. Since iscsit_get_login_rx() receives payload_length + padding bytes, where padding = ((-payload_length) & 3); any payload_length from 8189 to 8192 fills the whole 8192 byte buffer. The write stays in bounds, but no byte is left for a NUL terminator. The buffer is subsequently consumed as a C string. In the CHAP path chap_check_algorithm() calls kstrdup(a_str), and extract_param() calls strstr(in_buf, pattern) followed by strlen_semi(), none of which take a length. convert_null_to_semi() additionally rewrites every embedded NUL to ';', so even a payload made of well formed NUL separated key=value records is left without a terminator. These walk past the end of the object into adjacent slab memory. It is reachable by an unauthenticated initiator against a portal configured for CHAP; when authentication is not required iscsi_login_zero_tsih_s2() rewrites AuthMethod to None and the CHAP path is never entered. Allocate one extra byte. kzalloc() zeroes it and nothing ever writes to it, as every writer copies to offset 0 for at most MAX_KEY_VALUE_PAIRS bytes, so the buffer is always terminated. | ||||
| CVE-2026-90012 | 1 Linux | 2 Kernel, Linux Kernel | 2026-09-18 | 9.8 Critical |
| In the Linux kernel, the following vulnerability has been resolved: spi: Fix DMA mapping ownership on partial map failure If RX mapping fails after TX mapping succeeds, __spi_map_msg() unmaps TX but leaves tx_sg_mapped set. If TX mapping fails on a later transfer, mappings created for earlier transfers remain active. In both cases, cur_{tx,rx}_dma_dev have not yet been updated because they are assigned only after every transfer has been mapped. The subsequent spi_unmap_msg() may therefore unmap the TX mapping again or release earlier mappings using a NULL or stale device. Using a NULL device can trigger an oops. An empty SG table does not prevent the NULL dereference because dma_unmap_sg_attrs() accesses the device before checking the entry count. Publish both mapping devices before mapping starts and unwind all failures through __spi_unmap_msg(). This clears the mapping flags and releases each mapping once with the device that created it. Publishing the devices before the loop also refreshes them when no transfer needs mapping. No mapping flag is set in that case, so current users do not use the pointers as mapping owners. | ||||
| CVE-2026-92893 | 2 Red Hat, Redhat | 2 Red Hat Satellite 6, Satellite | 2026-09-18 | 4.3 Medium |
| A flaw was found in the foreman_ansible plugin's Ansible inventory API. The controller builds its host query using an unscoped Host.where call that does not enforce the search filter associated with the caller's view_hosts permission. An authenticated user whose host visibility is restricted by a permission filter can supply arbitrary host IDs within their organization and receive the full Ansible inventory for those hosts, including parameter values marked as hidden. | ||||
| CVE-2026-92729 | 1 Signoz | 1 Signoz | 2026-09-18 | 8.2 High |
| SigNoz versions 0.88.0 through 0.141.0 fail to apply authorization wrappers to trace-funnel analytics endpoints in the HTTP handler. Unauthenticated attackers can submit arbitrary funnel definitions to retrieve trace analytics including identifiers, durations, span counts, service topology, and error activity without credentials. | ||||
| CVE-2026-85705 | 2026-09-18 | 7.5 High | ||
| The Location Manager plugin for WordPress is vulnerable to generic SQL Injection via 'latitude' and 'longitude' REST API Parameters in all versions up to, and including, 2.3.38 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The injection is triggered when the orderby=lat_lon parameter is supplied, and affects multiple publicly accessible REST endpoints including geodir/v2/locations/cities, /regions, /countries, and /neighbourhoods via both the get_locations() and get_neighbourhoods() functions. | ||||
| CVE-2026-92249 | 2026-09-18 | 6.1 Medium | ||
| The Qi Addons For Elementor plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 's' parameter in all versions up to, and including, 1.11 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires the Table of Contents widget to be placed on a template that renders on the WordPress search-results page (e.g., a sitewide header or footer template) with the 'Limit ToC to Main Page Content' option left at its default value of No, so the widget scans the search-results heading that reflects the unsanitized `s` parameter. | ||||
| CVE-2026-15275 | 2026-09-18 | 7.5 High | ||
| The WP Multi Store Locator Pro plugin for WordPress is vulnerable to generic SQL Injection via the 'store_locatore_search_radius' parameter in all versions up to, and including, 4.5.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The injection occurs in a numeric, unquoted SQL context, meaning WordPress's wp_magic_quotes() addslashes-based protection cannot neutralize the payload, and the AJAX handler is registered on wp_ajax_nopriv_make_search_request with no nonce or capability check, making it fully accessible without authentication. | ||||
| CVE-2026-15004 | 2026-09-18 | 5.4 Medium | ||
| The FileBird – WordPress Media Library Folders & File Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via image alt text in all versions up to, and including, 6.5.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. | ||||
| CVE-2026-14323 | 2026-09-18 | 7.5 High | ||
| The Printcart Web to Print Product Designer for WooCommerce plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 2.8.5 via the 'mockups' parameter. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. A valid nonce is obtainable by unauthenticated users via the companion nbd_check_use_logged_in nopriv AJAX endpoint, which freely mints and returns a nbdesigner-get-data nonce to any visitor; additionally, if the NBDESIGNER_ENABLE_NONCE constant is disabled, even this nonce gate is bypassed entirely. | ||||
| CVE-2026-75961 | 2026-09-18 | 4.9 Medium | ||
| The NEX-Forms – Ultimate Forms Plugin for WordPress plugin for WordPress is vulnerable to generic SQL Injection via the 'additional_params' parameter in all versions up to, and including, 9.3.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with custom-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The operator allowlist applied by get_table_records() when building its own WHERE fragment is not enforced on the same tainted additional_params array when it is forwarded to get_total_records(), leaving the SQL sink unprotected. | ||||
| CVE-2026-92554 | 2026-09-18 | 6.1 Medium | ||
| The ShopLentor – All-in-One WooCommerce Growth & Store Enhancement Plugin plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via Query-String Parameter Name in all versions up to, and including, 3.5.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. The vulnerability is triggered via the WL: Product Horizontal Filter widget, which reflects attacker-supplied query-string parameter names from the current URL into option element value attributes without escaping, allowing payload breakout from the value="..." attribute context. | ||||
| CVE-2026-89953 | 1 Linux | 1 Linux Kernel | 2026-09-18 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: mtd: mtdoops: free page bitmap when the backing MTD is removed mtdoops_notify_add() allocates oops_page_used when the configured MTD device is registered. mtdoops_notify_remove() detaches from that device but leaves the bitmap allocated. If the same MTD device is later registered again, the add path allocates a new bitmap and overwrites the old pointer, leaking one vmalloc allocation per remove/add cycle. This is only visible when the backing MTD device can disappear and be registered again while mtdoops remains loaded, so the usual static MTD case does not expose it. Free the bitmap after unregistering the dumper and flushing the pending workers, then clear the pointer and page count before a later attach can allocate fresh state. Clearing the pointer also keeps the module exit path from freeing the same bitmap a second time after a remove event. | ||||
| CVE-2026-89956 | 1 Linux | 1 Linux Kernel | 2026-09-18 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: s390/vfio-ap: Fix missing lock required to access list of ap_matrix_mdev objects In order to traverse or add/remove ap_matrix_mdev objects in the matrix_dev->mdev_list, the matrix_dev->guests_lock mutex must be held. There are two functions that access the list without holding the mutex: vfio_ap_mdev_probe function ~~~~~~~~~~~~~~~~~~~~~~~~~~~ The vfio_ap_mdev_probe function uses the matrix_dev->mdevs_lock mutex to guard the add of a newly created ap_matrix_mdev object to the matrix_dev->mdev_list. This mutex does not protect list access; its purpose is to guard against concurrent access to fields contained in an ap_matrix_mdev object. This could lead to kernel memory corruption or use-after-free if another mdev is created or removed concurrently. The adding of an ap_matrix_mdev object to matrix_dev->mdev_list is now guarded by the matrix_dev->guests_lock which is the correct way to protect against concurrent mdev_list access. Also removed the following two lines of code because the matrix_mdev is allocated via vfio_alloc_device macro which uses kzalloc, so req_trigger and cfg_chg_trigger are already zero-initialised when the struct is allocated before the call to vfio_register_emulated_iommu_dev. This prevents a window whereby these triggers are set to NULL after the device is exposed to userspace. matrix_mdev->req_trigger = NULL; matrix_mdev->cfg_chg_trigger = NULL; vfio_ap_mdev_for_queue function ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The status_show function that supports display of the status attribute of the devices in /sys/bus/ap/devices calls the vfio_ap_mdev_for_queue function which iterates the matrix_dev->mdev_list to find the object representing the queue device whose status is to be displayed. In order to traverse this list, the matrix_dev->guests_lock mutex must be held. To fix this, the guests_lock mutex is taken prior to taking the matrix_dev->mdevs_lock mutex in the status_show function. It is taken there rather than the vfio_ap_mdev_for_queue function - where it is needed - because it must be taken prior to the mdevs_lock mutex in order to adhere to the proper locking order and prevent a lockdep splat; also because the mdevs_lock is needed there to access fields within the matrix_mdev object in that function. See the vfio-ap-locking.rst in the linux kernel tree. | ||||
| CVE-2026-89959 | 1 Linux | 1 Linux Kernel | 2026-09-18 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: s390/vfio-ap: Fix control domain removal in vfio_ap_mdev_cfg_remove The vfio_ap_config_remove function uses the bitmap_andnot function to clear bits from the matrix_mdev->matrix.adm bitmap (specifies the control domains assigned to the mdev). This prevents the explicitly unplugged control domains from being removed the KVM guest. The bitmap_and function is used instead. | ||||
| CVE-2026-89964 | 1 Linux | 1 Linux Kernel | 2026-09-18 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: parisc: eisa: Fix infinite loop when parsing invalid IRQ value When an invalid value is passed via the "eisa_irq_edge=" kernel command line parameter (e.g. "eisa_irq_edge=16,5"), eisa_irq_setup() prints an error message and continues without advancing the current position. As a result the same invalid value is parsed again and again, causing an infinite loop while the kernel boots. Advance to the next comma-separated entry, or stop parsing when there is no next entry, before continuing so that the remaining entries are processed normally. | ||||
