Affected files ============== The file(s) affected by this issue are: fs/afs/cell.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/13403945c2385653e282dacda304dce2a25fdb53 https://git.kernel.org/stable/c/2b169eedbb96f37f3f33d7b496d8283194988980 https://git.kernel.org/stable/c/bf55969d9188380eb539bd216850bac27bc2e272 https://git.kernel.org/stable/c/bef5514f6b6cb4bed9061f4b628d6be1cf26a39e https://git.kernel.org/stable/c/fbfe75c81bff2359a03e85cf84293484cf60fcb9 https://git.kernel.org/stable/c/8afb1a787a2802caf1895dd96745cfd6790a6f95 https://git.kernel.org/stable/c/91d8f8e5fd34d3aed26f0fe6cf52b3f71de66cc6 https://git.kernel.org/stable/c/fc10c0ecf06f2981af5d04357612b00051e03e9e
