Affected files ============== The file(s) affected by this issue are: drivers/rtc/rtc-mt6397.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/3867f0bbb94773d41e789257abec0d14f37da217 https://git.kernel.org/stable/c/79fa3f5758d8712df0678df98161f948fc4370e5 https://git.kernel.org/stable/c/6ecd4d5c28408df36a1a6f0b1973f633c949ac1f https://git.kernel.org/stable/c/d77f28c1bc9d3043a52069fe42e4a26fbf961ebd https://git.kernel.org/stable/c/82bfea344e8f7e9a0e0b1bf9af27552baa756620 https://git.kernel.org/stable/c/865051de2d9eaa50630e055b73921ceaf3c4a7fc https://git.kernel.org/stable/c/58a729c55ce3a432eb827fdaa24c7909cd3b0a6b https://git.kernel.org/stable/c/da38e86d6cf6dd3bc65c602d998f357145aa1a0b https://git.kernel.org/stable/c/d3b43eb505bffb8e4cdf6800c15660c001553fe6
