Need to copy the call\nto ieee80211_tdls_prep_mgmt_packet() since the existing\nWLAN_TDLS_DISCOVERY_REQUEST already falls through to it.","modified":"2026-10-15T02:47:34.996989859Z","published":"2026-10-14T13:27:50.200Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98421.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/038e1d126304fd25d507fd4e671232df57bd1799"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1c0a5c96473b9e7a5f4c453ef6a13dc0f5589a4b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6bae6ef511a29ef12ab969adeea691067d4d5d74"},{"type":"WEB","url":"https://git.kernel.org/stable/c/742c762bee59c973684f70dfed7de4945d3141e2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d0afa5395c46d73ad2090aa50209886e84f179bd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fce36d242a18ddf64731d816a37564103172da11"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98421.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98421"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6f7eaa47e1de30159277f91f1145a6687f13ffd9"},{"fixed":"6bae6ef511a29ef12ab969adeea691067d4d5d74"},{"fixed":"d0afa5395c46d73ad2090aa50209886e84f179bd"},{"fixed":"742c762bee59c973684f70dfed7de4945d3141e2"},{"fixed":"fce36d242a18ddf64731d816a37564103172da11"},{"fixed":"1c0a5c96473b9e7a5f4c453ef6a13dc0f5589a4b"},{"fixed":"038e1d126304fd25d507fd4e671232df57bd1799"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98421.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.17.0"},{"fixed":"6.1.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.112"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.54"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98421.json"}}],"schema_version":"1.9.0"}
