CVE-2024-21467Network attack vector

Memory disclosure via beacon frame buffer over-read

Published Aug 5, 2024 · Updated Aug 5, 2024

Buffer over-read in Qualcomm Snapdragon WLAN firmware allows remote attackers to disclose memory through crafted beacon or probe frames. During client-side scan entry generation, the WLAN host communication path reads beyond the received frame buffer while handling beacon or probe data. No privileges or user interaction are required; adjacent memory can be exposed, and Qualcomm records an availability impact without describing its failure mode.
