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.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Low · affected: Red Hat Enterprise Linux 10 · no fix planned: Red Hat Enterprise Linux 10 · updated 2026-09-29 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-89886.json)","depth":"sunlit","depthScore":30,"depthScoreParts":{"impact":30.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":210017,"id":"CVE-2026-89886","ts":1790235654119,"field":"cvss","old":null,"new":"5.5"},{"seq":210016,"id":"CVE-2026-89886","ts":1790235654119,"field":"severity","old":"none","new":"medium"}]}
