If the write lock acquisition is interrupted, the function returns without calling pm_runtime_put_autosuspend(), leaking the runtime PM reference acquired for the device and keeping the GPU awake. Drop the runtime PM reference on the interrupted down_write_killable() error path before returning. (cherry picked from commit ec30a576c2d4c0364549e6c04218f50704ef56c8) The Linux kernel CVE team has assigned CVE-2026-98519 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/gpu/drm/amd/amdgpu/amdgpu_debugfs.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/fc5606ac91642d0f184b83ab833148c457c3c331 https://git.kernel.org/stable/c/2c1a643942caae938ea84df2648a9b0c136e09be https://git.kernel.org/stable/c/e016347fb1829489e062ea51a98a51f48b1d582d https://git.kernel.org/stable/c/c28e74395ab09922bbf5be42bc5a6ed1ba4f3c37 https://git.kernel.org/stable/c/2556dd3a36beb3a11041ef01b5e9762e2157909f https://git.kernel.org/stable/c/2b86ab1bd6673c525adda88819d7658ba9e784ec
