Affected files ============== The file(s) affected by this issue are: drivers/mtd/maps/physmap-versatile.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/995fb2874bb5696357846a91e59181c600e6aac8 https://git.kernel.org/stable/c/d10855876a6f47add6ff621cef25cc0171dac162 https://git.kernel.org/stable/c/80b1465b2ae81ebb59bbe62bcb7a7f7d4e9ece6f https://git.kernel.org/stable/c/941ef6997f9db704fe4fd62fc01e420fdd5048b2 https://git.kernel.org/stable/c/d5730780e9ea84e5476752a47c749036c6a74af5 https://git.kernel.org/stable/c/a74322d4b897ddc268b340c4a397f6066c2f945d https://git.kernel.org/stable/c/babd7b0124650ab71a6487e38588b8659b3aa2dc https://git.kernel.org/stable/c/77087a04c8fd554134bddcb8a9ff87b21f357926
