Affected files ============== The file(s) affected by this issue are: drivers/gpu/drm/amd/amdgpu/amdgpu_device.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/29fd416e0e08aa6d5a97fd313749d08d83de0826 https://git.kernel.org/stable/c/276028fd9b60bbcc68796d1124b6b58298f4ca8a https://git.kernel.org/stable/c/3e849a93bff40f0c88a8aafba062b1de0ec2797b https://git.kernel.org/stable/c/9877a865d62c9c3e0f4cc369dc9ca9f7f24f5ee9
