CVE-2025-68223

A flaw was identified in the Linux kernel’s Radeon DRM driver involving self-deadlock risk when checking whether a dma_fence_ops::signaled fence has been signaled. In certain execution paths, the fence lock is also the wait queue lock for Radeon, and attempting to make forward progress on the wait queue while holding an unknown-state fence lock could result in a self-deadlock. Upstream patches remove the unnecessary queue progress attempt during the is_signaled check, eliminating the deadlock scenario while still correctly handling false signal results
