CVE-2026-99053

A flaw was found in the Linux kernel's Transparent Inter-Process Communication (TIPC) subsystem. This flaw allows a local user to cause a denial of service (DoS) or potentially escalate privileges on the system. The issue occurs because link configuration handlers release read locks without properly incrementing the node reference counter during node lookups. Consequently, a race condition with background cleanup routines can lead to a use-after-free condition when accessing stale node pointers.
