If kcalloc() fails, gb_lights_release() iterates the\nnon-zero count and dereferences light->channels, which is NULL.\n\nAllocate channels first and only then publish channels_count so the\ncleanup path can't walk a NULL pointer.","published":"2026-05-27T14:17:15.000Z","lastModified":"2026-06-17T10:52:50.000Z","status":"Analyzed","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":0.00123,"percentile":0.02028,"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 (0.12%).
