{"id":"CVE-2026-74412","summary":"wifi: rtw88: fix wrong pci_get_drvdata type in AER handlers","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: rtw88: fix wrong pci_get_drvdata type in AER handlers\n\nrtw88 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.\n\nUse ieee80211_stop_queues/wake_queues instead, consistent with\nevery other queue stop/start path in the driver.","modified":"2026-08-16T03:48:35.141317388Z","published":"2026-08-15T05:59:19.354Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74412.json","cna_assigner":"Linux"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"cdb82c80b9349ed1d9ce6b49856128e04f4effc9"},{"fixed":"1ef3d1338d94ec41f58fbfb6ba7742a27ea61d89"},{"fixed":"d7920797f721f944861f3c48ffb2b73f84b631fe"},{"fixed":"706183dbef4a79d120d4e928f693bea50df496f8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-74412.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.17.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-74412.json"}}],"schema_version":"1.9.0"}
