A race condition vulnerability in the Linux kernel's AMD GPU driver (drm/amd/display) related to non-atomic read/modify/write operations on IRQ control registers has been resolved. The issue involves the GLOBAL_SYNC_STATUS register, which controls hardware IRQ sources for the output timing generator. Due to non-atomic operations, a race can occur between disabling and acknowledging IRQs, potentially causing timeouts on high refresh rate panels. The fix introduces a driver-wide spinlock to atomize these operations, preventing the race condition. Join the discussion | GCVE Database | 10/18/2026, 18:31:58 UTC Added: 10/18/2026, 19:40:28 UTC |
