CVE-2025-27073Network attack vector

Transient service interruption via NDP assertion

Published Aug 6, 2025 · Updated Aug 6, 2025

Reachable assertion in Qualcomm Snapdragon WLAN firmware allows remote attackers to interrupt service while creating an NDP instance. The proprietary WLAN firmware reaches an assertion during NDP instance creation, but Qualcomm has not published the triggering field or code path. Unauthenticated network access is sufficient; exploitation causes a transient service interruption without reported data disclosure or modification.
