{"id":"CVE-2026-98700","summary":"wifi: mac80211: set info-\u003eband for 802.3 encap offload frames","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211: set info-\u003eband for 802.3 encap offload frames\n\nUnlike the 802.11 TX paths, ieee80211_8023_xmit() does not set\ninfo-\u003eband from the channel context on non-MLD interfaces. It stays at\n0, so ieee80211_get_tx_rates() uses the wrong band for these frames.\n\nSet it the same way as ieee80211_build_hdr(): drop the frame if there is\nno channel context, and leave the band at 0 on MLD interfaces.","modified":"2026-10-19T02:47:12.209371432Z","published":"2026-10-18T15:46:30.043Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98700.json"},"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/2d9c5525bbc1a548cdc9c4def3cd7fbfc7c66b5b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4febc02cd02f021f2b6d0768332be643ef14a12d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/93c1b247224a32f546b616a8fe87b9bab20f0a7f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9cedbfde1450028f530e9af950f53491fcaebfeb"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98700.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98700"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"50ff477a8639fa1fbbeecb5a6f2f8b6c5557ecec"},{"fixed":"93c1b247224a32f546b616a8fe87b9bab20f0a7f"},{"fixed":"9cedbfde1450028f530e9af950f53491fcaebfeb"},{"fixed":"2d9c5525bbc1a548cdc9c4def3cd7fbfc7c66b5b"},{"fixed":"4febc02cd02f021f2b6d0768332be643ef14a12d"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98700.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.7.0"},{"fixed":"6.12.113"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.56"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98700.json"}}],"schema_version":"1.9.0"}
