Linux hwe edge: In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix AMDGPU_INFO_READ_MMR_REG There were multiple issues in that code. (CVE-2026-53293)CVE-2026-53293 0 In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix AMDGPU_INFO_READ_MMR_REG There were multiple issues in that code. First of all the order between the reset semaphore and the mm_lock was wrong (e.g. copy_to_user) was called while holding the lock. Then we allocated memory while holding the reset semaphore which is also a pretty big bug and can deadlock. Then we used down_read_trylock() instead of waiting for the reset to finish. (cherry picked from commit 361b6e6b303d4b691f6c5974d3eaab67ca6dd90e) Join the discussion | GCVE Database | 06/26/2026, 20:17:00 UTC Added: 07/17/2026, 10:15:41 UTC |
A vulnerability in the Linux kernel's AMDGPU driver related to the AMDGPU_INFO_READ_MMR_REG functionality was resolved. (CVE-2026-53293)CVE-2026-53293 0 A vulnerability in the Linux kernel's AMDGPU driver related to the AMDGPU_INFO_READ_MMR_REG functionality was resolved. The issues included incorrect locking order, memory allocation while holding a semaphore leading to potential deadlocks, and improper use of down_read_trylock instead of waiting for reset completion. These flaws could cause denial of service due to deadlocks or hangs. Join the discussion | GCVE Database | 06/26/2026, 21:32:17 UTC Added: 07/08/2026, 13:21:26 UTC |
