Since the managed\nsingle and double bit IRQ handlers use altdev(dci->pvt_info) as their data, an\nIRQ firing between freeing dci and unregistering the IRQs could dereference\nthe freed memory.\n\nRelease the devres group first so the managed IRQs are unregistered\nbefore the dci structure is freed.\n\n## Affected\n\n- `Linux >= 588cb03ea208b303e6dee7e916f329043fd0fc26 < 865f3bdebbc9b34012358c377c9b15154f95f33b`\n- `Linux >= 588cb03ea208b303e6dee7e916f329043fd0fc26 < 87364b19b3fe4e6dbf88d6acf6db4ec87e7dfbba`\n- `Linux >= 588cb03ea208b303e6dee7e916f329043fd0fc26 < eef3b67f9c6782127163b631c9043011a68016e2`\n- `Linux 4.7`\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":[]}
