Memory disclosure via WLAN frame buffer over-read
Published Aug 5, 2024 · Updated Aug 5, 2024
Buffer over-read in Qualcomm WLAN HOST firmware allows remote attackers to disclose memory via crafted beacon or probe-response frames. The STA receive path reads beyond a frame-handling buffer while processing untrusted beacon or probe-response data; Qualcomm has not published the exact parser or failed bounds operation. Network access requires a transmitter capable of delivering the crafted WLAN management frame, and exploitation can expose memory or interrupt wireless service without privileges or user interaction.
