Affected files ============== The file(s) affected by this issue are: drivers/gpu/drm/mcde/mcde_dsi.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/87c35bbefdfa3c5edfb8c80f5c04717aaacc629d https://git.kernel.org/stable/c/f57699a9b66ea11f000f56d1f1179059239b8690 https://git.kernel.org/stable/c/3123ae6fdd4013d24a3a4877084b14e917faae5c https://git.kernel.org/stable/c/7214902de5b1fb2b632a7b8b3b9540e41aabab38 https://git.kernel.org/stable/c/32c827e30bb44ae809950a9efab59e98e44d30e5 https://git.kernel.org/stable/c/3a149169e4a2f9127022fec6ef5d71b4e804b3b9
