CVE-2025-68223

CVE-2025-68223 concerns the Linux kernel code path for DRM/Radeon fence handling. The fix removes an attempted forward progress on the queue inside is_signaled, preventing a potential self-deadlock when the fence lock also serves as the wait-queue lock. The underlying issue was that dma-fence_ops...
