CVE-2026-53197

A flaw was found in the iptfs module of the Linux kernel. This issue, an ABBA deadlock, occurs when iptfsdestroystate attempts to cancel a timer while holding a spinlock that the timer's callback also tries to acquire. This circular dependency can cause the system to become unresponsive, leading ...
