CVE-2025-47354 is a use-after-free vulnerability categorized under CWE-416, discovered in the Digital Signal Processor (DSP) service of Qualcomm Snapdragon chipsets. The vulnerability arises from improper memory management during buffer allocation, leading to memory corruption. This flaw affects a broad range of Qualcomm products, including FastConnect modules (6200, 6700, 7800), Snapdragon mobile platforms (4 Gen 2, 6 Gen 1), wearable platforms (W5+ Gen 1), and various wireless connectivity chips (WCD, WCN, WSA series). Exploitation requires local access with low privileges and does not require user interaction, making it easier to exploit in controlled environments. The CVSS v3.1 score of 7.8 reflects high impact on confidentiality, integrity, and availability, indicating that successful exploitation could allow attackers to execute arbitrary code, escalate privileges, or cause denial of service. The vulnerability is particularly critical because the DSP handles sensitive operations such as audio processing, sensor data, and wireless communications, which could be leveraged for persistent and stealthy attacks. No patches or exploits are currently publicly available, but the wide deployment of affected chipsets in smartphones, wearables, and IoT devices makes this a significant concern for device security and user privacy.

For European organizations, the impact of CVE-2025-47354 is substantial due to the widespread use of Qualcomm Snapdragon chipsets in mobile devices, wearables, and IoT equipment. Successful exploitation could lead to unauthorized data access, manipulation of sensitive communications, or disruption of critical services relying on these devices. This is especially concerning for sectors such as telecommunications, finance, healthcare, and government, where device integrity and confidentiality are paramount. The vulnerability could be exploited to bypass security controls, leading to data breaches or service outages. Additionally, the local access requirement means insider threats or compromised devices could be leveraged to launch attacks. The lack of user interaction requirement increases the risk of automated or stealthy exploitation in environments where physical or logical access to devices is possible. The potential for privilege escalation and persistent compromise could undermine trust in mobile and IoT ecosystems across Europe.

1. Immediate coordination with device manufacturers and Qualcomm to obtain and deploy firmware or software patches once available. 2. Implement strict access controls on devices using affected Snapdragon chipsets to limit local access to trusted personnel only. 3. Employ endpoint detection and response (EDR) solutions capable of monitoring anomalous DSP or memory-related activities. 4. Enforce device hardening practices, including disabling unnecessary services that interact with the DSP. 5. Regularly audit and inventory devices to identify those containing vulnerable Snapdragon components. 6. Educate users and administrators about the risks of local access exploitation and encourage secure device handling. 7. For organizations deploying IoT or wearable devices, segment networks to isolate vulnerable devices and reduce attack surface. 8. Monitor threat intelligence feeds for emerging exploit techniques or public patches related to CVE-2025-47354 to respond promptly. 9. Consider deploying runtime memory protection technologies where feasible to mitigate use-after-free exploitation. 10. Develop incident response plans specifically addressing potential exploitation of embedded chipset vulnerabilities.
