CVE-2022-33283Network attack vector

Memory disclosure via unchecked WLAN frame length

Published Jan 6, 2023 · Updated Apr 9, 2025

Buffer over-read in Qualcomm Snapdragon WLAN firmware allows remote attackers to disclose memory through a malformed WLAN frame. The frame parser reads beyond the supplied buffer because it processes frame fields without first verifying the received frame length. No privileges or user interaction are required; exploitation exposes adjacent firmware memory and can interrupt WLAN service without altering data.
