CVE-2024-20080Network attack vector

Remote privilege escalation via improper certificate validation

Published Jul 1, 2024 · Updated Aug 1, 2024

Improper certificate validation in MediaTek chipset GNSS service allows remote attackers to elevate privileges without interaction. The GNSS certificate-verification path fails to validate a certificate correctly; MediaTek has not disclosed the affected function or precise validation omission. No prior execution privileges or user interaction are required, and successful exploitation grants elevated privileges remotely.
