Overview
Affected versions of this package are vulnerable to Improper Input Validation in the close_all_cached_dirs process. An attacker can cause kernel memory disclosure, arbitrary kernel memory write, or denial of service by triggering a race condition between unmount operations and cached directory cleanup via malicious SMB server responses or network injection.
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
