CVE-2023-53204

CVE-2023-53204 affects the Linux kernel af_unix subsystem. The root cause is a data race on the unix_inflight field: user->unix_inflight is modified under spin_lock(unix_gc_lock), while too_many_unix_fds() reads it locklessly, enabling a race between unix_attach_fds and the unix_inflight acces...

The vulnerability of the af_unix component in the Linux operating system kernel allows a attacker to trigger a Denial-of-Service (DoS) attack.

The vulnerability of the afunix component in the Linux operating system’s kernel is related to errors in reading beyond the boundary in the function unixgc. Exploiting this vulnerability can allow an attacker to trigger a Denial-of-Service attack...

kernel: af_unix: Fix garbage collector racing against connect()

A flaw was found in the Linux kernel, where the management of inter-process communication uses AFUNIX sockets. The issue arises from a race condition where a partially initialized socket with specific permissions carrying SCMRIGHTS is improperly handled during garbage collection. This situation...
