About this tag
The mt76 driver is a Linux kernel module for MediaTek Wi-Fi chipsets, commonly found in modern laptops and embedded devices. Discussions on WindowsForum cover security vulnerabilities in this driver, such as CVE-2026-46136, a buffer underflow in the MT7921's country-location-control logic that can cause driver hangs or incorrect transmit power, and CVE-2024-42225, a memory initialization flaw fixed by replacing skb_put with skb_put_zero. While these are Linux kernel bugs, they matter to Windows users because many laptops use MediaTek radios that rely on the mt76 driver in dual-boot or virtualized environments. Microsoft's Azure Linux is also affected, as noted in MSRC attestations. The tag highlights how driver-level flaws in Linux can impact cross-platform hardware and enterprise cloud infrastructure.
