Affected files ============== The file(s) affected by this issue are: fs/ext4/namei.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/133ff0d78f1b160de011647bb65807195ca5d1ca https://git.kernel.org/stable/c/aca593e6070e21979430c344e9cb0b272a9e7e10 https://git.kernel.org/stable/c/a02d7f5b24193aed451ac67aad3453472e79dc78 https://git.kernel.org/stable/c/2d64e7dada22ab589d1ac216a3661074d027f25e https://git.kernel.org/stable/c/fe192515d2937b8ed2d21921b558a06dd2031d21 https://git.kernel.org/stable/c/9d4b2e4c36bb88d57018c1cbc8b6a0c4b44a7f42 https://git.kernel.org/stable/c/1a00a393d6a7fb1e745a41edd09019bd6a0ad64c
