{"id":"CVE-2026-74413","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-74413","summary":"wifi: rtw89: fix wrong pci_get_drvdata type in AER handlers","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: rtw89: fix wrong pci_get_drvdata type in AER handlers\n\nrtw89 stores an ieee80211_hw pointer via pci_set_drvdata() at probe\ntime, but io_error_detected() and io_resume() retrieve it as a\nnet_device pointer.  This causes netif_device_detach/attach to\noperate on an ieee80211_hw struct, reading and writing at wrong\noffsets.  The adjacent io_slot_reset() already does it correctly.\n\nUse ieee80211_stop_queues/wake_queues instead, consistent with\nevery other queue stop/start path in the driver.\n\nTested on RTL8852CE by calling the handlers from a test module\nbefore and after the fix.","published":"2026-08-15T05:59:20.021Z","modified":"2026-08-18T03:56:57.760002265Z","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/7068c379cf9aa8afe4dce4d9d82390187aa9c4d0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/aefc30e4a829c1683f6ae999df7f9310c27eae6c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c1907b9a4fa9cb33d11a9af138374dd2e93f7a93"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74413.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74413"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-18T03:56:57.760002265Z"}}
