| In the Linux kernel, the following vulnerability has been resolved:
tty: vcc: hold port lock when clearing tty pointer in vcc_cleanup
vcc_cleanup() sets port->tty to NULL without holding port->lock, racing
with vcc_event() LDC callbacks that read port->tty under port->lock and
then use tty->port. This can cause a use-after-free when the callback
dereferences tty->port after cleanup has already destroyed and freed it. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: cdns3: fix use-after-free in cdns3_gadget_exit()
cdns3_gadget_start() arms two works on system_freezable_wq:
pending_status_wq for the deferred ep0 status stage and aligned_buf_wq
for realigned request buffers. Both handlers use the cdns3_device the
works are embedded in, and cdns3_pending_setup_status_handler() also
calls the ep0 request completion.
cdns3_gadget_exit() does not wait for these works. It frees all
endpoints and aligned buffers and drops the last reference to the
gadget device, which frees priv_dev, so a work queued before the exit
can run after the free.
Fix this by waiting for both works after the gadget driver is unbound
and the IRQ is freed, when no new work can be queued, and before the
endpoints and buffers are released.
This issue was found by an in-house static analysis tool. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: typec: tipd: fix uninitialized typec_partner_desc in tps6598x_connect()
tps6598x_connect() passes a stack-allocated typec_partner_desc to
typec_register_partner() after initializing only usb_pd, accessory and
identity.
typec_register_partner() copies attach and deattach from the descriptor
into the partner. With those fields left unset, garbage function pointers
may be stored and later invoked from typec_partner_link_device() when a USB
device is linked to the port. Uninitialized pd_revision and usb_capability
similarly leak stack data through partner sysfs.
Zero-initialize the descriptor so optional callbacks remain NULL and the
remaining fields are zero. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: core: clear both ep_in and ep_out for non-ep0 control endpoints
In usb_enable_endpoint(), non-zero control endpoints (where
usb_endpoint_xfer_control(&ep->desc) is true) populate both
dev->ep_in[epnum] and dev->ep_out[epnum] with the same struct
usb_host_endpoint pointer.
However, usb_disable_endpoint() only clears either dev->ep_out[epnum] or
dev->ep_in[epnum] depending on the direction bit of epaddr when
reset_hardware is set, leaving the opposite direction's array slot
pointing to the disabled/freed endpoint.
Clear both dev->ep_out[epnum] and dev->ep_in[epnum] when disabling a
non-ep0 control endpoint with reset_hardware set, and update the
function kerneldoc accordingly.
Tested in QEMU against Linux 7.3.0-rc3 using dummy_hcd and raw-gadget to
enumerate a USB device with a non-zero control endpoint
(bEndpointAddress 0x01, bmAttributes USB_ENDPOINT_XFER_CONTROL),
verifying that both dev->ep_in[1] and dev->ep_out[1] are cleared when
the interface is disabled. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: dwc3: gadget: fix IRQ storm on invalid event buffer count
When dwc3_check_event_buf() reads a GEVNTCOUNT value exceeding the
event buffer length, commit 63ccd26cd1f6 ("usb: dwc3: gadget: check
that event count does not exceed event buffer length") returns IRQ_NONE
without writing back GEVNTCOUNT. Since the DWC3 interrupt is
level-triggered, the uncleared IRQ source keeps the line asserted,
causing a tight IRQ storm that accumulates 99,900 unhandled interrupts
and triggers spurious.c:184 BUG -> kernel panic.
The resulting call stack:
__report_bad_irq+0xac/0xc8
note_interrupt+0x340/0x468
handle_irq_event+0xac/0xc0
handle_fasteoi_irq+0x120/0x228
gic_handle_irq+0x68/0x108
...
kernel BUG at kernel/irq/spurious.c:184
To reproduce, write a bogus value exceeding the event buffer length
directly to the GEVNTCOUNT register:
devmem <DWC3_BASE + 0xc40c> 4 0x1004
Write the bogus count back to GEVNTCOUNT to clear the IRQ source,
consistent with the stale event clearing pattern in
dwc3_event_buffers_setup(), and schedule error recovery to
reinitialize the controller. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: storage: sierra_ms: reject short SWoC info transfers
sierra_get_swoc_info() requests sizeof(struct swoc_info) (60) bytes
from the device via usb_control_msg(), but its callers only treat a
negative return value as failure. A device that answers the
vendor-specific GetSwocInfo request with a short IN transfer is
therefore accepted, leaving the tail of the freshly allocated
(kmalloc(), non-zeroing) swoc_info buffer uninitialized.
truinst_show() subsequently prints swocInfo->rev, swocInfo->LinuxSKU
and swocInfo->LinuxVer from that buffer into the world-readable
(0444) "truinst" sysfs attribute. An emulated/malicious USB device
(VID 0x1199, PID 0x0fff) can exploit this to disclose up to 5 bytes
of stale kernel heap memory (kmalloc-64) to unprivileged userspace,
once per sysfs read, indefinitely. On kernels built without
init_on_alloc this leaks recently freed heap contents.
Only accept the transfer when the full structure was received.
sierra_ms_init() already retries failed queries, so well-behaved
devices are unaffected. |
| In the Linux kernel, the following vulnerability has been resolved:
binder: fix leaked fd fixups on TF_UPDATE_TXN supersede
When a TF_UPDATE_TXN transaction supersedes a pending async transaction
in a frozen process, the outdated transaction is freed with kfree()
directly. This skips binder_free_txn_fixups(), leaking all
binder_txn_fd_fixup entries and their fget()'d struct file references.
The leaked file refcounts never reach zero, so the struct file objects
are permanently pinned in memory. They survive process exit and
accumulate across invocations until file-max exhaustion.
Every other transaction cleanup path (binder_free_transaction(),
binder_transaction() error paths, binder_release_work()) correctly
calls binder_free_txn_fixups(). Add the missing call before kfree()
in the t_outdated cleanup block. |
| In the Linux kernel, the following vulnerability has been resolved:
binder: fix is_failure flag for superseded transaction cleanup
When a TF_UPDATE_TXN transaction supersedes a pending async transaction,
binder_release_entire_buffer() is called with is_failure=false. Since the
superseded transaction was never delivered, binder_apply_fd_fixups() was
never called and no fds were installed in the target process.
With is_failure=false, the BINDER_TYPE_FDA cleanup handler interprets
stale buffer contents as installed fd numbers and passes them to
binder_deferred_fd_close(), closing unrelated file descriptors.
Pass is_failure=true since the transaction was never delivered to the
target, matching the semantics of all other undelivered-transaction
cleanup paths. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu/gfx6: fix firmware leak on teardown
The firmware requested in gfx_v6_0_init_microcode() is not released
when the GFX block is torn down, leaking the firmware resources.
Add gfx_v6_0_free_microcode() and call it from gfx_v6_0_sw_fini()
to release the PFP, ME, CE and RLC firmware.

| Missing Authorization vulnerability in WPGraphQL WPGraphQL wp-graphql allows Retrieve Embedded Sensitive Data.This issue affects WPGraphQL: from n/a through 2.23.1. |
| The Animated Number Counters plugin for WordPress is vulnerable to generic SQL Injection via the 'counterid' parameter in all versions up to, and including, 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 editor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This is a second-order SQL injection: the write path correctly uses $wpdb->prepare(), but that protection is not carried forward to the read path, where the retrieved value is concatenated unsanitized into unprepared queries in both a single-quoted string context and a bare numeric context. |
| Heap-based buffer overflow in Windows Error Reporting allows an unauthorized attacker to execute code over a network. |
| Heap-based buffer overflow in DNS Server allows an authorized attacker to disclose information over a network. |
| The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.1.0 via the 'ID' parameter due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with author-level access and above, to modify arbitrary courses created by other instructors — overwriting their title, content, and status — and reassign ownership of those courses to themselves. This is possible because Input::sanitize_array() preserves attacker-supplied POST keys (including 'ID') without stripping them, and WordPress interprets a non-empty ID in the wp_insert_post() argument array as an update to the existing post rather than a new insert. |
| A flaw was found in xorg-x11-server. A use-after-free vulnerability, where the application accesses memory after it has already been released, occurs in the Present extension because window notification entries are not properly unlinked before cleaning up window resources. An authenticated local X client can exploit this flaw by creating cross-window notifications and subsequently destroying the target window. Successful exploitation primarily results in a Denial of Service (DoS) via an X server crash, and may potentially lead to information disclosure. |
| A flaw was found in xorg-x11-server. The GLX (OpenGL Extension to the X Window System) interface fails to verify that incoming data sizes do not exceed allocated buffer limits when handling large rendering requests. An authenticated local client can exploit this vulnerability by sending a specially crafted request, triggering a heap-based buffer overflow. Successful exploitation can result in arbitrary code execution with the privileges of the X server or cause a Denial of Service (DoS) by crashing the application. |
| A flaw was found in xorg-x11-server. A local authenticated client can exploit this flaw by sending a crafted input device ungrab request with an unvalidated modifier value. This lack of validation causes the server to perform an out-of-bounds write on the heap, resulting in memory corruption that can lead to a denial of service (DoS) or potential arbitrary code execution. |
| A flaw was found in xorg-x11-server. An authenticated local user can trigger an out-of-bounds heap memory read by sending specially crafted X Keyboard Extension (XKB) requests with inconsistent key range parameters. This flaw leads to information disclosure, allowing the user to read sensitive data from the server's heap memory. |
| A flaw was found in xorg-x11-server. A local user can exploit a use-after-free condition—where the software attempts to access memory after it has been freed—by establishing a passive input grab and removing an input device. When subsequent input events are processed, the server dereferences the dangling device pointer. This flaw can lead to arbitrary code execution or a Denial of Service (DoS) via an X server crash. |
| A flaw was found in the curl command-line tool. When configured to follow redirects to Secure File Transfer Protocol (SFTP) or Secure Copy Protocol (SCP) destinations, curl fails to apply user-specified Secure Shell (SSH) host verification settings. A malicious server can exploit this flaw by redirecting requests to an untrusted server, causing the connection to proceed without validating the remote host's identity. This failure can enable an attacker to intercept communications, leading to sensitive information disclosure. |
