{"id":"CVE-2026-90368","summary":"wifi: mt76: mt7915: unwind state on add_interface failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7915: unwind state on add_interface failure\n\nWhen mt76_wcid_alloc() fails, mt7915_add_interface() returned without\nclearing the vif_mask/omac_mask bits it had already set, without removing\nthe firmware dev info added earlier, and without clearing a monitor_vif\npointer to the vif mac80211 is about to free. mac80211 does not call\nremove_interface() for a failed add, so the indices and firmware dev\nentry leaked permanently and testmode could dereference the stale\nmonitor_vif. Add a proper error unwind.","modified":"2026-09-18T03:48:37.749545898Z","published":"2026-09-17T16:09:10.084Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90368.json","cna_assigner":"Linux"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/218fdf0fcb796b8d281dbdd4a6144c5a8fc7fd0f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2fb6480c52f611338e1b0abe5e6219be1fc9ab75"},{"type":"WEB","url":"https://git.kernel.org/stable/c/507eddb8175a67df5086354b92d6a4fd7f6f1f96"},{"type":"WEB","url":"https://git.kernel.org/stable/c/71bf9de2ab3fb2c54bedb0b4c9b468d2e1d55280"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90368.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90368"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"b619e01380eedf24e8d26a367e94e0ccaeb0c3dd"},{"fixed":"218fdf0fcb796b8d281dbdd4a6144c5a8fc7fd0f"},{"fixed":"507eddb8175a67df5086354b92d6a4fd7f6f1f96"},{"fixed":"71bf9de2ab3fb2c54bedb0b4c9b468d2e1d55280"},{"fixed":"2fb6480c52f611338e1b0abe5e6219be1fc9ab75"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90368.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.19.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90368.json"}}],"schema_version":"1.9.0"}
