CVE-2025-47344 is a time-of-check to time-of-use (TOCTOU) race condition vulnerability classified under CWE-367, discovered in Qualcomm Snapdragon platforms. This vulnerability arises from improper synchronization when handling sensor utility operations, leading to memory corruption. The affected products include a broad spectrum of Qualcomm chipsets and modules such as CSRA, FastConnect, QCA, QCM, QCS, SM series, Snapdragon mobile platforms (including Gen 1, Gen 2, 4G, 5G variants), and various wireless connectivity components (WCD, WCN, WSA series). The flaw allows an attacker with high privileges (PR:H) and local access (AV:L) to exploit the race condition without requiring user interaction (UI:N). Successful exploitation can compromise confidentiality, integrity, and availability of the system, potentially leading to privilege escalation, arbitrary code execution, or denial of service. The CVSS v3.1 score is 6.7, reflecting a medium severity level due to the requirement for local high privileges and the complexity of exploitation. No public exploits or patches are currently available, indicating the need for vigilance and proactive mitigation. The vulnerability affects embedded and mobile devices relying on Qualcomm Snapdragon platforms, which are prevalent in smartphones, IoT devices, automotive systems, and industrial equipment.

For European organizations, the impact of CVE-2025-47344 can be significant, especially for sectors relying heavily on Qualcomm Snapdragon-based devices such as telecommunications, automotive, manufacturing, and critical infrastructure. Exploitation could lead to unauthorized access to sensitive data, disruption of device functionality, or full system compromise. In mobile environments, this could affect employee devices, leading to data breaches or lateral movement within corporate networks. In embedded systems, such as automotive or industrial IoT, exploitation could disrupt operational technology, causing safety risks or operational downtime. The requirement for high privileges and local access limits remote exploitation but does not eliminate insider threats or attacks via compromised devices. The broad range of affected chipsets means many devices in use across Europe could be vulnerable, increasing the attack surface. The absence of known exploits currently reduces immediate risk but underscores the importance of timely patching and monitoring.

1. Monitor Qualcomm and device vendors for official patches and apply them promptly once released. 2. Implement strict access controls and privilege separation on devices using affected Snapdragon platforms to limit local high-privilege access. 3. Employ runtime protections such as memory protection mechanisms and exploit mitigation technologies (e.g., ASLR, DEP) where supported. 4. Conduct regular security audits and monitoring of sensor utility operations and related processes to detect anomalous behavior indicative of exploitation attempts. 5. For enterprise mobile devices, enforce mobile device management (MDM) policies that restrict installation of untrusted applications and limit privilege escalation. 6. In embedded and IoT deployments, isolate critical systems and restrict physical and network access to reduce the risk of local exploitation. 7. Educate internal teams about the risks of local privilege escalation vulnerabilities and the importance of device hygiene. 8. Prepare incident response plans that include scenarios involving exploitation of local vulnerabilities on embedded platforms.
