CVE-2022-25749Network attack vector

Service interruption via mDNS frame buffer over-read

Published Oct 19, 2022 · Updated Apr 22, 2025

Buffer over-read in Qualcomm Snapdragon WLAN allows remote attackers to interrupt wireless service via crafted mDNS frames. The WLAN mDNS frame parser reads beyond the supplied packet buffer when it processes malformed frame data. No authentication or user action is required; successful reachability causes only a transient wireless-service interruption, with no reported data exposure or modification.
