CVE-2026-25289 is a critical stack-based buffer overflow in Qualcomm WLAN firmware. The flaw arises while processing Device Capability Extended attributes in certain Neighbor Awareness Networking (NAN) Service Discovery frames containing invalid length values. Improper handling of the supplied attribute length causes memory corruption in the WLAN firmware. Qualcomm lists affected products across multiple Snapdragon, FastConnect, QCA, QCN, WCN, IPQ, Networking Pro, and Snapdragon Wear platform families.
