Affected files ============== The file(s) affected by this issue are: net/netfilter/nft_chain_filter.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/9489e214ea8f2a90345516016aa51f2db3a8cc2f https://git.kernel.org/stable/c/70f17b48c86622217a58d5099d29242fc9adac58 https://git.kernel.org/stable/c/af149a46890e8285d1618bd68b8d159bdb87fdb3 https://git.kernel.org/stable/c/e5888acbf1a3d8d021990ce6c6061fd5b2bb21b4 https://git.kernel.org/stable/c/36a0a80f32209238469deb481967d777a3d539ee https://git.kernel.org/stable/c/01acb2e8666a6529697141a6017edbf206921913
