The driver registered the IRQ before constructing these\nqueues and destroyed them before freeing the IRQ, so the handler's lifetime\nwas not contained by the resources it accesses.\n\nInitialize the queues with interrupts masked, request the IRQ, and then\nswitch to interrupt mode. On removal, reset the device and free the IRQ\nbefore destroying the queues. Also reset the device before destroying the\nqueues if IRQ registration fails, because the device already has their DMA\naddresses.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
