CVE-2022-49541 is a double-free vulnerability in the Linux kernel CIFS mounting code. Following a CIFS mount error, the code can free the same pointer twice because it lacks a check to prevent the repeated free. The resulting kernel-memory corruption condition can cause system instability and may permit local privilege escalation or arbitrary code execution.
