BADGARBAGE.c CVE-2026-53361 — an unprivileged, container-escapable use-after-free in the AFUNIX socket garbage collector. This is the single-vector MSGPEEK only version. The Bug The AFUNIX GC reclaims "in-flight" sockets that form unreachable reference cycles. A concurrent MSGPEEK on an in-flight...

Vulnerability of the unix_gc() component. Igor, MSG_PEEK. Let’s talk about the kernels of the Linux operating system, which allow a hacker to cause a service failure.

Vulnerability of the unixgc component. Igor, MSGPEEK. The kernels of the Linux operating system are vulnerable to pointer dereferencing when the pointer has reached its expiration time. Exploiting this vulnerability can allow an attacker to cause a service failure...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: afunix: Set gcinprogress to true in unixgc. Igor Ushakov reported that unixgc could run with gcinprogress being false if the work is scheduled while it is running: Thread 1 Thread 2 Thread 3 -------- -------- --------...

kernel: af_unix: Set gc_in_progress to true in unix_gc()

A flaw was found in the Linux kernel's afunix component. A race condition exists within the unixgc garbage collection function where the gcinprogress flag may not be correctly set. This could lead to unixpeekfpl misinterpreting garbage collection status when handling MSGPEEK operations, potential...

stomper 5e2741e is vulnerable to Denial of Service. A malicious client can send partial STOMP frames and keep the TCP connections open, which, combined with the broker s use of edge-triggered epoll EPOLLET and MSGPEEK in recv, causes sockets to enter a permanent half-read state. When enough such...

CVE-2026-74434

The CVE-2026-74434 issue affects the Linux kernel rxrpc path: when reading an OOB message with MSG_PEEK, rxrpc_recvmsg_oob() unlinks from recvmsg_oobq but always moves the message onto pending_oobq, risking the sk_buff rbnode linkage being overwritten. This allows the skb to be reachable from bot...
