If the workqueue\nallocation fails, the error path unregisters the switchdev and netdevice\nnotifiers, but leaves the blocking notifier registered.\n\nAdd a separate error label for the workqueue allocation failure path and\nunregister the switchdev blocking notifier there.","published":"2026-08-15T05:52:51.067Z","modified":"2026-08-16T03:48:31.947712830Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"5.15.212"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/17f113e7b622dc850992ade540181717de6a8561"},{"type":"WEB","url":"https://git.kernel.org/stable/c/483be61b4a9a6df3b7cb277e8f189e082dee4cb8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8a3c44a003176282ee4306b7c96e5a536c6f0707"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cf419c869e0d03aad4b6f4ecf0a813851930dfe7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d6084c47389fd6978a5d66b0d58206a548c792a9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e5afc6d3fabdf1f605d63c4b34a3df6c359e81f3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fbc65b17508ed5464b7106e7fa5f15251ca1b603"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72109.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72109"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-16T03:48:31.947712830Z"}}
