Adding a GFX reset as workaround just before sending the MP1_UNLOAD message avoids this failure. The Linux kernel CVE team has assigned CVE-2024-36026 to this issue. Affected and fixed versions =========================== Fixed in 6.1.87 with commit bd9b94055c3d Fixed in 6.6.28 with commit 1e3b8874d55c Fixed in 6.8.7 with commit 7521329e5493 Fixed in 6.9 with commit 31729e8c21ec Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2024-36026 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: drivers/gpu/drm/amd/pm/swsmu/smu13/smu_v13_0_4_ppt.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/bd9b94055c3deb2398ee4490c1dfdf03f53efb8f https://git.kernel.org/stable/c/1e3b8874d55c0c28378beb9007494a7a9269a5f5 https://git.kernel.org/stable/c/7521329e54931ede9e042bbf5f4f812b5bc4a01d https://git.kernel.org/stable/c/31729e8c21ecfd671458e02b6511eb68c2225113
