Overview

Affected versions of this package are vulnerable to Use After Free in the afs_find_server process. An attacker can cause memory corruption or potentially execute arbitrary code by triggering a sequence where a stale peer app data pointer is dereferenced after the associated server object has been freed. This can be achieved by manipulating the timing of address list updates and subsequent RxRPC calls, leading to use of freed memory.

Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
