CVE-2026-89820: CVE-2026-89820: güvenlik açığı
Açıklama (NVD)
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: fix dc_lock leak on GPU reset error paths On GPU reset, dm_suspend() takes dc_lock and leaves it for dm_resume() to drop. If amdgpu_dm_commit_zero_streams() or dm_dmub_hw_init() fails, the function returns with the lock still held. The matching resume path is then skipped, so every later dc_lock take hangs. Release the cached DC state and unlock before returning the error.
