MediaTek WLAN Out-of-Bounds Write Vulnerability Leading to Privilege Escalation

A high-severity out-of-bounds write vulnerability has been identified in the WLAN access point firmware of certain MediaTek chipsets. This issue arises from an incorrect bounds check, which could allow for remote (proximal/adjacent) escalation of privilege without requiring additional execution privileges or user interaction. The vulnerability affects the MT6890, MT7915, MT7916, MT7981, and MT7986 chipsets.

Impact

Exploitation of this vulnerability could lead to unauthorized escalation of privileges, allowing a user to gain elevated rights or access within the system.
