CVE-2025-27045 is a buffer over-read vulnerability classified under CWE-126, discovered in the video driver component of Qualcomm Snapdragon chipsets, including FastConnect 6900, 7800, and various other models like QCC2072 and WCD series. The flaw occurs during the processing of batch command execution, where the driver improperly handles memory boundaries, allowing an attacker with local low-privilege access to read beyond intended memory buffers. This results in information disclosure, potentially leaking sensitive data stored in memory. The vulnerability does not require user interaction and has a CVSS 3.1 base score of 6.1, indicating medium severity. The attack vector is local, with low complexity and privileges required, but no integrity or availability impact is noted. No public exploits have been reported yet, and Qualcomm has not released patches at the time of publication. The vulnerability affects a broad range of Snapdragon-based devices, commonly used in smartphones, IoT devices, and wireless communication modules, making it relevant for a wide user base. The flaw's exploitation could be leveraged by attackers who have gained local access, such as through compromised applications or insider threats, to extract confidential information from device memory.

For European organizations, the primary impact of CVE-2025-27045 is the potential leakage of sensitive information from devices running affected Qualcomm Snapdragon chipsets. This could include corporate mobile devices, IoT endpoints, and embedded systems used in critical infrastructure or enterprise environments. Confidentiality breaches could lead to exposure of proprietary data, credentials, or cryptographic material, increasing the risk of further attacks such as lateral movement or privilege escalation. Although the vulnerability does not affect system integrity or availability, the information disclosure could undermine trust and compliance with data protection regulations like GDPR. The local attack vector limits remote exploitation, but insider threats or malware with local access could exploit this flaw. The impact is particularly significant for sectors relying heavily on mobile and wireless technologies, including telecommunications, manufacturing, and government agencies. Failure to address this vulnerability could result in targeted espionage or data theft campaigns within European markets.

To mitigate CVE-2025-27045, European organizations should implement several targeted measures beyond generic patching advice. First, restrict local access to devices with affected Qualcomm Snapdragon chipsets by enforcing strict endpoint security policies, including application whitelisting and privilege management to prevent unauthorized code execution. Monitor device logs and behavior for anomalies indicative of exploitation attempts, such as unusual memory access patterns or batch command executions. Employ mobile device management (MDM) solutions to enforce security configurations and promptly deploy vendor patches once available. For IoT deployments, segment networks to isolate vulnerable devices and limit exposure. Additionally, conduct regular security audits and penetration testing focusing on local privilege escalation and memory disclosure vectors. Engage with Qualcomm and device manufacturers to obtain timely firmware updates and validate patch effectiveness. Educate users and administrators about the risks of local exploitation and the importance of maintaining device hygiene. Finally, consider deploying runtime memory protection technologies where feasible to detect and prevent buffer over-read attempts.
