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/38f1640db7f8bf57b9e09c5b0b8b205a598f1b3e https://git.kernel.org/stable/c/5edcb0d6729b88f192ec8b0896aaf581e3593c9c https://git.kernel.org/stable/c/72ecb1dae72775fa9fea0159d8445d620a0a2295
