Affected files ============== The file(s) affected by this issue are: arch/powerpc/platforms/52xx/mpc52xx_lpbfifo.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/be9caf2c936f15a9c3f9111e62bdde6357312f90 https://git.kernel.org/stable/c/f4ad0a7f0e78d65d38921ab2bef234e49be78b10 https://git.kernel.org/stable/c/e4002f293e5b44e57d2930513cca0dff32249812 https://git.kernel.org/stable/c/9bf842ffdd216b9f94d5b051b5d8b815f2426538 https://git.kernel.org/stable/c/40b4be399e0db7073dec5a0de5ca9994f7e31e58 https://git.kernel.org/stable/c/0accd460dc7bbe5f55e41a8867c63db9d07b3ec8 https://git.kernel.org/stable/c/cbda93665a3857324f5c79e45769a83c78183199 https://git.kernel.org/stable/c/fb3ef6a5af4b003502c940ea50c0f55b06ebbfc9 https://git.kernel.org/stable/c/5836947613ef33d311b4eff6a32d019580a214f5
