Affected files ============== The file(s) affected by this issue are: drivers/gpu/drm/amd/amdgpu/amdgpu_uvd.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/1facad2a78c1a8aeecc36eb4d560c7f1e10ce198 https://git.kernel.org/stable/c/499907e5d46e575e96967c0230a0a6af980a17ab https://git.kernel.org/stable/c/cbf1c84bf5cac2b3742ea3d2085fa713424465cc https://git.kernel.org/stable/c/a930c54cb67200de8bc0de87480d09ece7dcd85d https://git.kernel.org/stable/c/2abcdc5f738574e7fcdd9417575dffb877fdc26f https://git.kernel.org/stable/c/e304c3e0d9ce251887be1f274aa0ed52219d5fd7 https://git.kernel.org/stable/c/0acdf1a575f59bd46717d5c487d84575af5bee8f https://git.kernel.org/stable/c/9fca434208f1f9ab977feac62df8ebb1cc7ce893
