For the others, this field value remain NULL by\ndefault.\nThe cancel_work_sync function is unconditionally called in\nmtk_jpeg_release function, even for the variants that do not use the\nworkqueue. This call generates a WARN_ON print in __flush_work because\nthe workqueue callback function presence check fails in __flush_work\nfunction (used by cancel_work_sync).\n\nSo, to avoid these warnings, call cancel_work_sync only if a workqueue\ncallback is defined in platform data.","published":"2026-07-25T10:17:18.000Z","lastModified":"2026-09-04T15:57:50.000Z","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":0.00122,"percentile":0.01966,"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":"low","text":"Lower severity and a low EPSS score (0.12%).
