{"id":"CVE-2022-49646","summary":"wifi: mac80211: fix queue selection for mesh/OCB interfaces","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211: fix queue selection for mesh/OCB interfaces\n\nWhen using iTXQ, the code assumes that there is only one vif queue for\nbroadcast packets, using the BE queue. Allowing non-BE queue marking\nviolates that assumption and txq-\u003eac == skb_queue_mapping is no longer\nguaranteed. This can cause issues with queue handling in the driver and\nalso causes issues with the recent ATF change, resulting in an AQL\nunderflow warning.","modified":"2026-04-02T08:27:47.740730Z","published":"2025-02-26T02:23:51.083Z","related":["SUSE-SU-2025:1027-1","SUSE-SU-2025:1176-1","SUSE-SU-2025:1183-1","SUSE-SU-2025:1194-1","SUSE-SU-2025:1241-1","SUSE-SU-2025:1263-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49646.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/41ecab279a70dced9005f4d55fa0fcde8938603f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/444be5a02b77f3b7a8ac9c1a0b074fbb3bd89cd0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/50e2ab39291947b6c6c7025cf01707c270fcde59"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5a9df31017999197b6e60535940f2f2fe1bd3b0d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e013ea2a51a94b903b396a8dff531a07d470335d"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49646.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-49646"},{"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":"1974da8b31e6ea9c96c21505ffcb546fa59add23"},{"fixed":"444be5a02b77f3b7a8ac9c1a0b074fbb3bd89cd0"},{"fixed":"e013ea2a51a94b903b396a8dff531a07d470335d"},{"fixed":"5a9df31017999197b6e60535940f2f2fe1bd3b0d"},{"fixed":"41ecab279a70dced9005f4d55fa0fcde8938603f"},{"fixed":"50e2ab39291947b6c6c7025cf01707c270fcde59"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-49646.json"}}],"schema_version":"1.7.5"}
