Description

A flaw was found in the Linux kernel. A race condition in the `act_ct` module, specifically during the flow table lookup, can lead to a Use-After-Free (UAF) vulnerability. This occurs because a critical lock is released prematurely, allowing a memory object to be freed while still in use. An attacker could potentially exploit this to achieve privilege escalation.
