Linux Kernel Memory Management Issue Affecting Unix Socket Communication

CVE-2026-53361

What is CVE-2026-53361?

A vulnerability in the Linux kernel relates to improper handling of the garbage collection status during socket communications. Specifically, the unix_gc() function may execute without properly setting gc_in_progress to true, potentially leading to erroneous behavior in the garbage collection process when multiple threads interact. This issue manifests when queued work might trigger race conditions where gc_in_progress does not correctly reflect the state of the garbage collection process, impacting the reliability of socket communication and garbage collection routines.
