Affected files ============== The file(s) affected by this issue are: drivers/input/misc/ims-pcu.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/a5dd47ea3904dedb1ae7a5fe0e6b44a458f0c5ec https://git.kernel.org/stable/c/1f7bdfbe791aacad77db87f044e78ef60a93ae0d https://git.kernel.org/stable/c/99c428d7ef644d3e394f3072f905040c16dab18d https://git.kernel.org/stable/c/47a9889a9325b87698b6d6eaf3187a9af6e4773d https://git.kernel.org/stable/c/d48795b5cd6828d36b707e8d62fc9e5c90e004ab
