This results in use-after-free.\n\nIf atomisp_register_i2c_module() fails, the media entity and control\nhandler are left initialized and dev is leaked.\n\ngc2235_remove() unconditionally calls media_entity_cleanup() and\nv4l2_ctrl_handler_free(), but these are not initialized at every\nerror path in gc2235_probe().\n\nReplace gc2235_remove() calls in the probe error paths with explicit\nunwind labels that free only the resources initialized at each point\nof failure, in reverse order of initialization.","published":"2026-08-28T08:16:50.000Z","lastModified":"2026-10-21T13:19:57.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00215,"percentile":0.11761,"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":"unknown","text":"Not yet scored.
