CVE-2025-47328 is a high-severity vulnerability identified in various Qualcomm Snapdragon and related wireless communication platforms. The vulnerability is classified as CWE-126, which corresponds to a buffer over-read condition. Specifically, this flaw occurs during the processing of power control requests that contain invalid antenna or stream values. When such malformed requests are handled, the system may transiently crash or become unresponsive, resulting in a denial-of-service (DoS) condition. The affected products include a broad range of Qualcomm chipsets and modules, such as FastConnect 7800, multiple Immersive Home platforms, IPQ series, QCA and QCN series, Snapdragon X72 and X75 5G Modem-RF systems, and various WCD, WCN, WSA, QCF, QFW, QMP, QXM, and SM series components. These components are widely used in mobile devices, wireless routers, IoT gateways, and other network infrastructure equipment. The vulnerability does not require any privileges or user interaction to exploit, and the attack vector is network-based (AV:N), making it remotely exploitable. The CVSS v3.1 score of 7.5 reflects a high severity due to the ease of exploitation and the impact on availability, although confidentiality and integrity are not affected. No known exploits are currently reported in the wild, and no patches have been linked yet. However, the broad product impact and the critical nature of network availability in affected devices make this vulnerability a significant concern for organizations relying on Qualcomm-based wireless infrastructure.

For European organizations, the impact of CVE-2025-47328 can be substantial, particularly for those relying on Qualcomm Snapdragon-based wireless infrastructure, including mobile devices, enterprise Wi-Fi access points, and IoT gateways. A successful exploitation could cause transient denial-of-service conditions, disrupting network connectivity and wireless communication. This could affect critical business operations, especially in sectors such as telecommunications, finance, healthcare, and manufacturing, where continuous network availability is essential. The transient DoS could lead to service interruptions, degraded user experience, and potential cascading effects on dependent systems. Given the remote exploitability without authentication or user interaction, attackers could launch attacks from external networks, increasing the risk of widespread disruption. Additionally, the vulnerability could be leveraged as part of a larger attack chain to degrade network infrastructure resilience. Although confidentiality and integrity are not directly impacted, the availability impact alone can cause significant operational and financial damage.

To mitigate CVE-2025-47328, European organizations should: 1) Monitor Qualcomm and device vendors for official patches or firmware updates addressing this vulnerability and prioritize their deployment across all affected devices. 2) Implement network-level protections such as intrusion detection and prevention systems (IDS/IPS) configured to detect anomalous power control request patterns or malformed antenna/stream values targeting Qualcomm chipsets. 3) Employ network segmentation to isolate critical wireless infrastructure components, limiting exposure to untrusted networks and reducing the attack surface. 4) Enforce strict access controls and network filtering rules to restrict unsolicited or malformed network traffic to vulnerable devices. 5) Engage with device manufacturers and service providers to verify the presence of vulnerable components and request timely remediation. 6) Conduct regular vulnerability assessments and penetration testing focused on wireless infrastructure to detect potential exploitation attempts. 7) Prepare incident response plans specifically addressing transient DoS scenarios affecting wireless connectivity to minimize downtime and operational impact.
