Affected files ============== The file(s) affected by this issue are: fs/nfsd/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/930cb4fe3ab4061be31f20ee30bb72a66f7bb6d1 https://git.kernel.org/stable/c/375fdd8993cecc48afa359728a6e70b280dde1c8 https://git.kernel.org/stable/c/2ac46606b2cc49e78d8e3d8f2685e79e9ba73020 https://git.kernel.org/stable/c/03524ccff698d4a77d096ed529073d91f5edee5d https://git.kernel.org/stable/c/a4948875ed0599c037dc438c11891c9012721b1d https://git.kernel.org/stable/c/8f244b773c63fa480c9a3bd1ae04f5272f285e89 https://git.kernel.org/stable/c/abb1f08a2121dd270193746e43b2a9373db9ad84
