1) Out-of-bounds read (CVE-ID: CVE-2026-74651)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to out-of-bounds read in rtw_get_wpa_ie() when parsing vendor-specific information elements from received management frames or WPA IE data. A remote attacker can send a specially crafted management frame or crafted IE data to disclose sensitive information.

The issue can be triggered by a short trailing vendor-specific information element whose length is 0 to 5 bytes.
