{"id":"CVE-2026-90357","summary":"wifi: mt76: mt7915: unlink TWT flow if the MCU rejects the agreement","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7915: unlink TWT flow if the MCU rejects the agreement\n\nThe flow is added to dev-\u003etwt_list before sending the agreement to the\nfirmware, but the error path leaves it linked while flowid_mask is\nnever set. The flow slot can then be reused and memset while still on\nthe list, corrupting twt_list, and station removal leaves a dangling\nentry behind that mt7915_mac_twt_sched_list_add() later walks.","modified":"2026-09-19T03:47:26.145821280Z","published":"2026-09-17T16:09:02.873Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90357.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/16a04441eab0dcd4d7126a6f66b370adbf28f96d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1bd5c4ed2b9045faf83315c54cd37a9b7c71b5c7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6bce0f1280c94af8314f895f404629da09f0788c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/beaa42b875965dbc3e80e46970e0bfa60a94c2db"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c09d1b15ed2dc49060303b16a296b7b8b7794cbe"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cabe239e95b4eebf5b6c3654087b66ff9425bc7b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90357.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90357"},{"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":"3782b69d03e714b8ff98b84c7426d8cef0e64d7c"},{"fixed":"c09d1b15ed2dc49060303b16a296b7b8b7794cbe"},{"fixed":"1bd5c4ed2b9045faf83315c54cd37a9b7c71b5c7"},{"fixed":"cabe239e95b4eebf5b6c3654087b66ff9425bc7b"},{"fixed":"6bce0f1280c94af8314f895f404629da09f0788c"},{"fixed":"beaa42b875965dbc3e80e46970e0bfa60a94c2db"},{"fixed":"16a04441eab0dcd4d7126a6f66b370adbf28f96d"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90357.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.188"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.157"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"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-2026-90357.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
