CVE-2024-20089Network attack vector

Remote service interruption via WLAN error mishandling

Published Sep 2, 2024 · Updated Sep 3, 2024

Incorrect error handling in MediaTek WLAN software on affected chipsets allows remote attackers to interrupt service over a network. MediaTek identifies the WLAN component and improper error handling but has not published the failing routine, triggering input, or exact crash path. Exploitation requires no authentication, added execution privileges, or user interaction; the reported consequence is limited to remote denial of service.
