Adjacent privilege escalation via WLAN integer overflow
Published Oct 14, 2025 · Updated Oct 14, 2025
Integer overflow in the MediaTek WLAN AP driver in SDK 7.6.7.2 and earlier allows remote attackers to gain elevated privileges. An undisclosed integer calculation overflows before an out-of-bounds memory write; MediaTek has not published the affected function or input field. Exposure requires proximity to an affected wireless access point, but requires neither prior privileges nor user interaction and can compromise confidentiality, integrity, and availability.
