Overview
Affected versions of this package are vulnerable to Use After Free in the lock_work process. An attacker can achieve kernel memory corruption and potential privilege escalation by cycling POSIX locks and inode eviction/reuse on AFS files they control, which can result in use-after-free conditions and arbitrary kernel write or control-flow hijack.
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
