If an\nendpoint parse or add fails partway through the loop, it jumps to\nerr_parse and returns without calling v4l2_async_nf_cleanup(), leaking\nevery v4l2_async_connection already added to the notifier's waiting\nlist.\n\nThe register-failure path just below already cleans up correctly, and\nthe caller only tears the notifier down (isys_notifier_cleanup()) once\nisys_notifier_init() has returned success. Clean up the notifier on the\nparse error path too.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
