{"id":"CVE-2026-89886","summary":"media: intel/ipu6: fix async notifier cleanup leak on parse error","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: intel/ipu6: fix async notifier cleanup leak on parse error\n\nisys_notifier_init() calls v4l2_async_nf_init() and then adds fwnode\nremote subdevs in a loop with v4l2_async_nf_add_fwnode_remote(). 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.","modified":"2026-09-18T03:48:33.704159010Z","published":"2026-09-16T10:31:50.497Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89886.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/27b7997be552ee37b3e01beacfeb4131f1bebb5f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/abb1f808ceab5a3275f8a6b4e37cff17f9f781c1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dd5943aedbe4d7eb46158cb35078257733ac48b6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/eee6069e4e9511e814a33a75e403f7e863f70394"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89886.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89886"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"f50c4ca0a82003b8a542c3332fd292cf1bc355a2"},{"fixed":"dd5943aedbe4d7eb46158cb35078257733ac48b6"},{"fixed":"27b7997be552ee37b3e01beacfeb4131f1bebb5f"},{"fixed":"eee6069e4e9511e814a33a75e403f7e863f70394"},{"fixed":"abb1f808ceab5a3275f8a6b4e37cff17f9f781c1"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89886.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.10.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.51"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89886.json"}}],"schema_version":"1.9.0"}
