Affected files ============== The file(s) affected by this issue are: drivers/soc/samsung/exynos-chipid.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/475b9b45dc32eba58ab794b5d47ac689fc018398 https://git.kernel.org/stable/c/5f80fd2ff8bfd13e41554741740e0ca8e6445ded https://git.kernel.org/stable/c/44a2572a0fdcf3e7565763690d579b998a8f0562 https://git.kernel.org/stable/c/4f51d169fd0d4821bce775618db024062b09a3f7 https://git.kernel.org/stable/c/4129760e462f45f14e61b10408ace61aa7c2ed30 https://git.kernel.org/stable/c/c8222ef6cf29dd7cad21643228f96535cc02b327
