Affected files ============== The file(s) affected by this issue are: arch/powerpc/platforms/cell/spufs/inode.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/829bd6139968e2e759f3928cf65ad0db1e302fe3 https://git.kernel.org/stable/c/410c787d89c92df4215d7b1a338e2c1a8aba6b9b https://git.kernel.org/stable/c/c4e72a0d75442237b6f3bcca10a7d81b89376d16 https://git.kernel.org/stable/c/a333f223e555d27609f8b45d75a08e8e1d36c432 https://git.kernel.org/stable/c/239ea3c34673b3244a499fd65771c47e5bffcbb0 https://git.kernel.org/stable/c/d04600f43569d48262e1328eaa1592fcefa2c19c https://git.kernel.org/stable/c/5a90b699844a5bb96961e5892e51cc59255444a3 https://git.kernel.org/stable/c/4a7448c83e117ed68597952ecaede1cebc4427a7 https://git.kernel.org/stable/c/0f5cce3fc55b08ee4da3372baccf4bcd36a98396
