| CVE-2026-80858 | 1 Linux | 1 Linux Kernel | 2026-09-11 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: fuse: publish io-uring queues with release semantics fuse_uring_create_queue() initializes a fuse_ring_queue and then publishes the pointer into ring->queues[qid] with WRITE_ONCE() under the fch->lock. There are several readers that may concurrently be fetching that pointer locklessly and then deferencing it. WRITE_ONCE() doesn't ensure ordering of the queue's field initialization before the ring->queues[qid] pointer assignment. The queue must be published with smp_store_release() so the field initialization is guaranteed to happen before. Readers in paths where the read may happen concurrently with the store need to use READ_ONCE() because any race involving a plain access is undefined. | ||||
| CVE-2026-80847 | 1 Linux | 1 Linux Kernel | 2026-09-11 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: tcp: clamp route advmss to TCP_MIN_MSS tcp_select_initial_window() assumes that callers never pass an MSS smaller than 1, but route-derived advmss values can violate that assumption. A too-small explicit RTAX_ADVMSS is one way to get there, but it is not the only one. The same divide-by-zero can also be reached through the "default advmss" path when RTAX_ADVMSS is left at 0 and the effective advmss is later driven down by route MTU and min_adv_mss. Introduce a tcp_dst_advmss() helper that clamps route advmss to TCP_MIN_MSS before TCP consumes it, and use it in the TCP paths that derive advmss from dst metrics. This keeps the effective MSS from dropping to zero before tcp_select_initial_window() rounds the receive window. | ||||
| CVE-2026-80841 | 1 Linux | 1 Linux Kernel | 2026-09-11 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: net/packet: defer vmalloc TX_RING free until skbs finish AF_PACKET TX_RING skbs keep a raw pointer to their ring frame. The skb page references preserve page-backed ring blocks after pg_vec is freed, but they do not preserve a vmalloc mapping. tpacket_destruct_skb() currently drops the pending reference before writing the timestamp and TP_STATUS_AVAILABLE to the frame. Move the decrement after those stores. The smp_wmb() in __packet_set_status() orders the frame stores before the decrement. Also recheck pending TX frames under pg_vec_lock before non-closing ring replacement, so a racing send cannot add a pending skb between the initial check and the ring swap. Ring allocation can produce a mixture of page-backed and vmalloc-backed blocks. Allocate deferred-work storage during TX ring setup when the first vmalloc-backed block is encountered, and keep its pointer in the pg_vec allocation header. If allocation fails, return -ENOMEM from ring setup. On socket close, a non-NULL pointer identifies a vmalloc-backed vector without a scan. If TX skbs remain, defer the whole vector to system_long_wq. After pg_vec is detached, a late destructor can skip the pending decrement. Use socket write-memory accounting as the deferred lifetime gate instead: an skb remains charged through its final sock_wfree(), after all ring-frame accesses. The delayed work retains a socket reference and reschedules itself until no TX skbs remain. Move pending_refcnt release to packet_sock_destruct() so late skb destructors and deferred cleanup can safely use it after packet_release(). Page-backed teardown remains synchronous, and no lock is added to the TX completion hot path. | ||||
| CVE-2026-88939 | 1 Knowns-dev | 1 Knowns | 2026-09-11 | 8.3 High |
| knowns through 0.33.0 exempts the project.set action from permission guard checks unconditionally, allowing read-only agent sessions to bypass restrictions. Attackers can invoke project.set to repoint the server at another project directory and obtain write access capabilities. | ||||
| CVE-2026-88940 | 1 Knowns-dev | 1 Knowns | 2026-09-11 | 5.3 Medium |
| knowns through 0.33.0 fails to validate the path query parameter in the workspace browse endpoint, allowing remote attackers to enumerate arbitrary directories on the host filesystem. Attackers can traverse the directory structure to locate project directories and identify targets for further exploitation. | ||||
| CVE-2026-88013 | 1 Rclone | 1 Rclone | 2026-09-11 | 3.7 Low |
| rclone is a command-line program to sync files and directories to and from different cloud storage providers. From 1.49.0 until 1.75.1, the HTTP backend attaches headers configured through --http-headers or headers= to requests in backend/http/http.go, while its fshttp.NewClient client follows redirects without a backend-specific http.Client.CheckRedirect policy. A configured remote that redirects to another host can therefore cause custom secrets such as X-Api-Key to be resent to that untrusted destination, and a same-host HTTPS-to-HTTP redirect can expose Authorization or Cookie headers in cleartext. Listing, stat, download, mount, and serve operations can trigger the leak during normal use. This issue is fixed in version 1.75.1. | ||||
| CVE-2026-87090 | 1 Hashicorp | 2 Consul, Consul Enterprise | 2026-09-11 | 8.3 High |
| Consul and Consul Enterprise are vulnerable to an authorization bypass in the catalog node-write path that may allow an authenticated attacker to delete another node's catalog registration and take over its node identity. An attacker with a token granting node-write permission on any single node name may exploit this issue if they can obtain the node ID of a node they do not control. This vulnerability (CVE-2026-87090) is fixed in Consul 2.0.4 and Consul Enterprise 1.21.18, 1.22.12 and 2.0.4. | ||||
| CVE-2026-87106 | 1 Hashicorp | 2 Consul, Consul Enterprise | 2026-09-11 | 6.5 Medium |
| Consul and Consul Enterprise are vulnerable to a denial of service in the native RPC listener that may allow an authenticated client to exhaust server memory before ACL authorization is evaluated. A client that can complete the internal RPC mTLS handshake may exploit this issue without holding a valid ACL token. This vulnerability (CVE-2026-87106) is fixed in Consul 2.0.4 and Consul Enterprise 1.21.18, 1.22.12 and 2.0.4. | ||||
| CVE-2026-11573 | 1 Qt | 1 Qt | 2026-09-11 | 7.5 High |
| Uncontrolled recursion (CWE-674) in the QDomDocument/QDomNode serialization path of the Qt XML module (QtXml, qtbase). QDomElementPrivate::save() and QDomNodePrivate::save() recurse mutually, consuming one stack frame per level of element nesting with no depth limit, no configurable bound and no error return. A document with deeply nested elements parses successfully but exhausts the call stack and terminates the process when serialized. Reachable via QDomDocument::toByteArray() (Qt 4.0 and later), QDomDocument::toString(), QDomDocument::toCString(), QDomNode::save(), and operator<<(QTextStream&, const QDomNode&). Denial of service only — no code execution and no memory disclosure. | ||||
| CVE-2026-85310 | 2 Adrian Tobey, Wordpress | 2 Groundhogg, Wordpress | 2026-09-11 | 6.5 Medium |

| CVE-2026-16118 | 1 Redhat | 1 Enterprise Linux | 2026-09-11 | 7.1 High |
| A flaw was found in xdgmime. A heap-based buffer overflow can be triggered in _xdg_mime_magic_parse_magic_line() in the xdgmimemagic.c file on little-endian systems when an attacker-controlled MIME magic file in a user-writable XDG data location (e.g., in the $XDG_DATA_HOME/mime/magic path) is parsed by an application performing MIME type detection (e.g., via g_content_type_guess()). When performing byte-swap, incorrect pointer arithmetic on the write side causes an out-of-bounds write of 2 bytes, resulting in an application crash or memory corruption. | ||||
| CVE-2026-81796 | 2 Wordpress, Wp Travel | 2 Wordpress, Wp Travel | 2026-09-11 | 7.3 High |

| CVE-2026-88011 | 1 Traefik | 1 Traefik | 2026-09-11 | N/A |
| Traefik is an open source HTTP reverse proxy and load balancer. Prior to 2.11.56, and from 3.0.0 until 3.7.12, a client-supplied dot-form header such as X.Authenticated.User survives ForwardAuth replacement and underscoreHeadersStrategy because Go treats it as distinct from X-Authenticated-User while normalization-prone CGI, WSGI, PHP, and NGINX backends collapse both names. A backend can consequently consume the client value instead of the identity Traefik asserted, allowing identity spoofing for any header managed by Traefik. The aliasHeadersStrategy protection is disabled by default and must be configured as delete or reject. The mitigation is available in 2.11.56 and 3.7.12. | ||||
| CVE-2026-88025 | 1 Mongodb | 1 C# Driver | 2026-09-11 | 8.3 High |
| Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB C# Driver can cause a caller-supplied structured file identifier to be interpreted as a query condition rather than as a literal identifier. An authenticated user who can influence the identifier passed by an affected application may obtain stored file content beyond the intended target or cause all GridFS file chunks in the affected bucket to be removed, rendering stored file content unreadable. The affected rename operation may also rename a stored file other than the intended target. | ||||
| CVE-2026-88021 | 1 Hashicorp | 2 Consul, Consul Enterprise | 2026-09-11 | 7.5 High |
| Consul and Consul Enterprise are vulnerable to an authorization bypass in the Connect service mesh that may allow a service to reach a destination it is not authorized to access. When building Envoy RBAC rules to enforce Connect intentions, Consul did not correctly escape certain characters in service names, namespaces, and partitions, causing the generated authorization rules to match more broadly than intended. This vulnerability (CVE-2026-88021) is fixed in Consul 2.0.4 and Consul Enterprise 1.21.18, 1.22.12 and 2.0.4. | ||||
| CVE-2026-81784 | 2 Marcin, Wordpress | 2 Wise Chat, Wordpress | 2026-09-11 | 8.1 High |
| Unauthenticated PHP Object Injection in Wise Chat <= 3.4 versions. | ||||
| CVE-2026-88004 | 1 Traefik | 1 Traefik | 2026-09-11 | N/A |
| Traefik is an open source HTTP reverse proxy and load balancer. From 3.2.0 until 3.7.13, Traefik entrypoint defenses aliasHeadersStrategy, underscoreHeadersStrategy, and forwardedHeaders inspect req.Header but not req.Trailer, allowing an unauthenticated client to submit an aliasing or trusted header name in an HTTP/1.1 chunked trailer or an HTTP/2 trailer. When the retry or buffering middleware reads the body before the reverse proxy clones the request, the attacker-controlled trailer value reaches a backend that merges trailers into the header namespace, bypassing the documented delete or reject behavior and potentially spoofing identity or forwarded routing data. This issue is fixed in 3.7.13. | ||||
| CVE-2026-87993 | 1 Hashicorp | 1 Tooling | 2026-09-11 | 7.7 High |
| The consul-template library is vulnerable to an information disclosure issue in its error handling path that may allow Vault secret values to appear in template error messages, log output, and downstream surfaces such as Nomad task events. This vulnerability (CVE-2026-87993) is fixed in consul-template 0.43.0. | ||||
| CVE-2026-45761 | 1 Oisf | 1 Suricata | 2026-09-11 | 3.3 Low |
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to versions 7.0.16 and 8.0.5, a crafted rule using mixed-case frame syntax could trigger a heap buffer overflow while Suricata is loading signatures. The issue is reached during rule parsing/loading rather than by network traffic alone. Versions 7.0.16 and 8.0.5 contain a fix. As a workaround, preprocess rules to check that frames are all lowercase and/or only load trusted rulesets. | ||||
| CVE-2026-88007 | 1 Traefik | 1 Traefik | 2026-09-11 | N/A |
| Traefik is an open source HTTP reverse proxy and load balancer. From 2.11.0 until 2.11.57 and 3.7.13, the HTTP/3 entrypoint ConnContext does not call service.AddTransportOnContext, so kerberosRoundTripper uses a shared backend transport instead of a transport dedicated to each frontend connection. With HTTP/3 enabled, a backend using connection-bound NTLM or Negotiate authentication, and backend keep-alive, an unrelated client can reuse a backend connection authenticated for a victim, read victim-only data, and act as that victim without the victim credentials. This issue is fixed in 2.11.57 and 3.7.13. | ||||
