In the Linux kernel, the following vulnerability has been resolved: dmaengine: dw-edma: Serialize abort state updates dw_edma_abort_interrupt() drops vc.lock before changing request and status. issue_pending() can acquire the lock in that small window, observe the old busy state, and skip starting queued descriptors. Then the abort handler overwrites the channel status as idle, leaving the new descriptors stranded for good. Keep descriptor completion and the state transition in the same critical section.
