{"id":"CVE-2026-46125","summary":"wifi: mac80211: remove station if connection prep fails","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211: remove station if connection prep fails\n\nIf connection preparation fails for MLO connections, then the\ninterface is completely reset to non-MLD. In this case, we must\nnot keep the station since it's related to the link of the vif\nbeing removed. Delete an existing station. Any \"new_sta\" is\nalready being removed, so that doesn't need changes.\n\nThis fixes a use-after-free/double-free in debugfs if that's\nenabled, because a vif going from MLD (and to MLD, but that's\nnot relevant here) recreates its entire debugfs.","modified":"2026-07-08T08:13:37.600141862Z","published":"2026-05-28T09:35:39.809Z","related":["ALSA-2026:26427","ALSA-2026:26428","ALSA-2026:27288","ALSA-2026:27789","openSUSE-SU-2026:10954-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46125.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/18fed0a209500bfea5c4c08609ec93855e4e500b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1c2b72ea89882aeb948340498391e69c58d466f1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/283fc9e44ff5b5ac967439b4951b80bd4299f4e4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9e28654f79f443bca9b29ff3ae7cf18abfba58a0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/afcbaed89cdc1a001b43270cbf5394bb4804270a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fe75fa1ac9a92990f7fc3d34b17808fd933071b2"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-46125.json"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:26427"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:26428"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:26462"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:26515"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:26563"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:27288"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:27708"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:27731"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:27735"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:27789"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-46125"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46125.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46125"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2482608"},{"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":"81151ce462e533551f3284bfdb8e0f461c9220e6"},{"fixed":"18fed0a209500bfea5c4c08609ec93855e4e500b"},{"fixed":"fe75fa1ac9a92990f7fc3d34b17808fd933071b2"},{"fixed":"afcbaed89cdc1a001b43270cbf5394bb4804270a"},{"fixed":"9e28654f79f443bca9b29ff3ae7cf18abfba58a0"},{"fixed":"1c2b72ea89882aeb948340498391e69c58d466f1"},{"fixed":"283fc9e44ff5b5ac967439b4951b80bd4299f4e4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-46125.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.0.0"},{"fixed":"6.1.176"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.140"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.88"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.30"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-46125.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
