Transient service interruption via FTM buffer over-read
Published Mar 4, 2024 · Updated Aug 12, 2024
Buffer over-read in Qualcomm WLAN Firmware allows remote attackers to interrupt service using a malformed 802.11az FTM frame. The proprietary Fine Time Measurement frame parser reads beyond the supplied frame buffer while processing a malformed protocol frame. No authentication or user interaction is required; the documented consequence is a transient WLAN service interruption.
