We weren't checking\nthe bounds on that value.\n\nCheck them.\n\nv2: Lower bounds check is unecessary because of idr_alloc\nalready rejecting negative numbers. Upper bounds check should\nbe KFD_SIGNAL_EVENT_LIMIT since the signal mode mappings might\nnot yet exist\n\n(cherry picked from commit 6853f1f6cbbeb3f53ebbbd7286536aeb2c5d5f50)","published":"2026-08-10T13:20:15.000Z","lastModified":"2026-08-19T17:20:40.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00173,"percentile":0.06637,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"unknown","text":"Not yet scored.
