CVE-2026-97985

The Linux kernel contains a vulnerability in the af_unix component where blocking recv(MSG_PEEK) operations could hog CPU resources. The issue occurs because manage_oob() skips Out-Of-Band (OOB) socket buffers and returns NULL for the last MSG_PEEK , failing to update the @last marker in unix_str...

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...
