Affected files ============== The file(s) affected by this issue are: fs/nfs/nfs4proc.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/c6aca4c7ba8f6d40a0cfeeb09160dd8efdf97c64 https://git.kernel.org/stable/c/dfad5d5e7511933c2ae3d12a8131840074c5a73d https://git.kernel.org/stable/c/b247a9828f6607d41189fa6c2a3be754d33cae86 https://git.kernel.org/stable/c/e83458fce080dc23c25353a1af90bfecf79c7369
