This causes netif_device_detach/attach to\noperate on an ieee80211_hw struct, reading and writing at wrong\noffsets.\n\nUse ieee80211_stop_queues/wake_queues instead, consistent with\nevery other queue stop/start path in the driver.","published":"2026-08-15T05:59:19.354Z","modified":"2026-08-18T03:56:57.604181856Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"6.18.40"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1ef3d1338d94ec41f58fbfb6ba7742a27ea61d89"},{"type":"WEB","url":"https://git.kernel.org/stable/c/706183dbef4a79d120d4e928f693bea50df496f8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d7920797f721f944861f3c48ffb2b73f84b631fe"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74412.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74412"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-18T03:56:57.604181856Z"}}
