Transient denial of service via WLAN frame parsing
Published Oct 7, 2024 · Updated Oct 7, 2024
Buffer over-read in Qualcomm Snapdragon WLAN firmware allows remote attackers to interrupt service via crafted probe or association response frames. The closed-source WLAN parser reads beyond a response-frame buffer while processing probe responses and association responses; Qualcomm has not disclosed the specific routine or length-check failure. No privileges or user interaction are required, but reachability requires delivery of a malicious WLAN management response and the documented consequence is transient denial of service only.
