Affected files ============== The file(s) affected by this issue are: drivers/gpu/drm/amd/amdgpu/sdma_v5_0.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/f6212bc1bbd936fd9f7d77168b0c8b0019477b64 https://git.kernel.org/stable/c/28337e5d7df429bac7de64b17f1a595147778caa https://git.kernel.org/stable/c/d20b5c139b2906bcd8ab4bfe5b8be500318161d1 https://git.kernel.org/stable/c/0027cb19b0449ad6babedb1af285a713ab05c97f https://git.kernel.org/stable/c/9e98ed3113943257ad6e5c1e6beddbdb482a70ad
