Adjacent information disclosure via incorrect WLAN bounds check
Published Jul 8, 2025 · Updated Jul 8, 2025
Out-of-bounds read in the MediaTek WLAN STA driver allows remote attackers to disclose memory via adjacent wireless input. An incorrect bounds check permits a read beyond a buffer boundary; MediaTek has not disclosed the affected routine or input field. Exploitation requires wireless proximity, needs neither privileges nor user interaction, and is limited to information disclosure.
