CVE-2026-53005

A flaw was found in the Linux kernel's af_unix component, specifically within its SOCKMAP feature. This vulnerability stems from the kernel's improper handling of Socket Control Message (SCM) attributes when data is passed to the SOCKMAP layer. This can lead to a use-after-free condition, which may allow an attacker to cause system instability or a denial of service. The issue also contributes to resource leaks of file descriptors and inaccurate reporting of file descriptor counts.
