How to fix?

Overview

Affected versions of this package are vulnerable to Out-of-bounds Write in the netfs_collect_read_results and netfs_collect_write_results functions due to missing memory barriers when accessing the subrequests list locklessly. An attacker can cause kernel memory corruption, privilege escalation, and arbitrary code execution by controlling the timing of network file system I/O completions from a malicious remote server.

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
