Memory corruption via unchecked PMK length
Published Dec 5, 2023 · Updated May 29, 2025
Classic buffer overflow in Qualcomm Snapdragon WLAN Host allows local users with high privileges to corrupt memory through PMK caching. The WLAN Host writes a supplied PMK length into its internal cache without checking the destination buffer size. Reachability requires local high-privilege access; successful corruption can compromise confidentiality, integrity, and availability.
