Affected files ============== The file(s) affected by this issue are: drivers/firmware/efi/capsule-loader.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/00cf21ac526011a29fc708f8912da446fac19f7b https://git.kernel.org/stable/c/950d4d74d311a18baed6878dbfba8180d7e5dddd https://git.kernel.org/stable/c/537e3f49dbe88881a6f0752beaa596942d9efd64 https://git.kernel.org/stable/c/4b73473c050a612fb4317831371073eda07c3050 https://git.kernel.org/stable/c/ddc547dd05a46720866c32022300f7376c40119f https://git.kernel.org/stable/c/11aabd7487857b8e7d768fefb092f66dfde68492 https://git.kernel.org/stable/c/62a5dcd9bd3097e9813de62fa6f22815e84a0172 https://git.kernel.org/stable/c/fccfa646ef3628097d59f7d9c1a3e84d4b6bb45e
