Affected files ============== The file(s) affected by this issue are: drivers/gpu/drm/panthor/panthor_sched.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/bfc5b91ab3ddddf636d8c1c050455bf4e14c912b https://git.kernel.org/stable/c/dd0b2976b7c0f4ea806855ed19ffad967d36610e https://git.kernel.org/stable/c/053522ba615888e874adc04e675d9ed2e13f35af https://git.kernel.org/stable/c/b39436d0ba1571dbcda69d20ec567344b3eecfc7
