Affected files ============== The file(s) affected by this issue are: drivers/media/platform/renesas/rcar_fdp1.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/418a8f3140e07f33bbd5a81625d0ef46c0732cef https://git.kernel.org/stable/c/9df630dafa1a59946d1da6f070d4cb64f14ea57c https://git.kernel.org/stable/c/1acb982e3616e70128994fdecf2368a259c8a489 https://git.kernel.org/stable/c/2322b262d2205720518785c2706a3283725ba402 https://git.kernel.org/stable/c/45b7461d914c867ef21c74798da8c42d13d3a0df https://git.kernel.org/stable/c/59c6addfaaaa09ff7654e4d8793cb16fd22a46d4 https://git.kernel.org/stable/c/48765ca7c6b71bf73a4cc8475a4bad9e2633cf61 https://git.kernel.org/stable/c/c766c90faf93897b77c9c5daa603cffab85ba907
