CVE-2023-28581Network attack vector

Memory corruption via malformed GTK key parsing

Published Sep 5, 2023 · Updated Feb 27, 2025

Memory corruption in Qualcomm Snapdragon WLAN firmware allows remote attackers to corrupt memory via crafted GTK key data elements. The closed-source parser processes received GTK keys in GTK KDE data without adequate buffer-bound restrictions; Qualcomm discloses no finer code-level locus. No privileges or user interaction are required, and successful exploitation can compromise confidentiality, integrity, and availability.
