CVE-2025-47320 is an out-of-bounds write vulnerability classified under CWE-787, discovered in Qualcomm Snapdragon chipsets. The vulnerability arises from improper memory handling during the processing of the Multi-Function Codec (MFC) channel configuration specifically triggered during music playback. This memory corruption flaw can be exploited by an attacker with local privileges (AV:L) and low complexity (AC:L) without requiring user interaction (UI:N). The vulnerability affects a vast array of Snapdragon platforms, including mobile, automotive, wearable, and IoT devices, spanning from older models like the Snapdragon 625 to the latest Snapdragon 8 Gen 3 Mobile Platform. The flaw allows an attacker to overwrite memory beyond allocated boundaries, potentially leading to arbitrary code execution, privilege escalation, or denial of service. The CVSS v3.1 score is 7.8, reflecting high impact on confidentiality, integrity, and availability. No patches are currently linked, and no known exploits have been reported in the wild. The vulnerability's exploitation scope is significant due to the widespread deployment of affected Snapdragon chipsets in consumer and enterprise devices globally.

For European organizations, the impact of CVE-2025-47320 is substantial due to the extensive use of Qualcomm Snapdragon chipsets in smartphones, automotive systems, and IoT devices. Successful exploitation could lead to unauthorized access to sensitive data, device control takeover, and disruption of critical services. Enterprises relying on mobile devices for secure communications or automotive manufacturers integrating Snapdragon platforms in connected vehicles may face risks of data breaches, operational interruptions, and safety hazards. The vulnerability could also affect wearable devices used in healthcare or industrial monitoring, potentially compromising personal data or operational integrity. Given the local attack vector, insider threats or malware with local access could leverage this flaw to escalate privileges and move laterally within networks. The absence of known exploits currently provides a window for proactive mitigation, but the broad affected device base increases the urgency for patching and risk management.

1. Monitor Qualcomm and device vendors for official patches and apply them promptly once available. 2. Restrict local access to devices running affected Snapdragon platforms by enforcing strong authentication and limiting administrative privileges. 3. Employ mobile device management (MDM) solutions to enforce security policies and remotely update or isolate vulnerable devices. 4. Conduct regular security audits and vulnerability assessments on devices incorporating affected chipsets, especially in enterprise and automotive environments. 5. Implement application whitelisting and endpoint protection to detect and prevent exploitation attempts that leverage local privilege escalation. 6. For automotive and IoT deployments, ensure network segmentation and robust intrusion detection to limit the impact of potential compromises. 7. Educate users and administrators about the risks of local exploitation and the importance of applying updates and avoiding untrusted software installations.
