Affected files ============== The file(s) affected by this issue are: drivers/power/supply/power_supply_core.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/8ea68b4e3fa9392ef9dae303abc8735a033c280f https://git.kernel.org/stable/c/5beadb55f4e36fafe5d6df5dcd5f85d803f3f134 https://git.kernel.org/stable/c/d21534ab4fd7883e1c8037a76671d4e8b6ea14cb https://git.kernel.org/stable/c/279af90e65cbdb3e5c4519b0043324d7876bc5ec https://git.kernel.org/stable/c/b8131efb89d9f837c9244f900f0fc2699fd1181d https://git.kernel.org/stable/c/104bb8a663451404a26331263ce5b96c34504049
