When the device is eventually unbound, mana_remove() is invoked\na second time. Without a NULL check, it dereferences gc->dev with\ngc == NULL, causing a kernel panic.\n\nAdd an early return if gdma_context or driver_data is NULL so the second\ninvocation is harmless. Move the dev = gc->dev assignment after the\nguard so it cannot dereference NULL.","published":"2026-06-26T20:17:23.000Z","lastModified":"2026-10-21T13:19:14.000Z","status":"Modified","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":5.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-476"],"affected":["linux/linux kernel"],"epss":{"score":0.00162,"percentile":0.0531,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.16%).
