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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/27b7997be552ee37b3e01beacfeb4131f1bebb5f","tags":[]},{"url":"https://git.kernel.org/stable/c/abb1f808ceab5a3275f8a6b4e37cff17f9f781c1","tags":[]},{"url":"https://git.kernel.org/stable/c/dd5943aedbe4d7eb46158cb35078257733ac48b6","tags":[]},{"url":"https://git.kernel.org/stable/c/eee6069e4e9511e814a33a75e403f7e863f70394","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
