CVE-2025-47362 is a buffer over-read vulnerability classified under CWE-126, discovered in various Qualcomm Snapdragon chipsets. The vulnerability arises when the chipset processes messages from clients containing invalid payloads, causing the system to read beyond the intended buffer boundaries. This results in information disclosure, potentially leaking sensitive data from memory. The affected Snapdragon versions include a broad spectrum of mobile and automotive platforms such as MSM8996AU, QAM series, QCA series, SA series, and the Snapdragon 820 Automotive Platform, among others. The CVSS v3.1 score is 6.1 (medium severity), with an attack vector classified as local (AV:L), low attack complexity (AC:L), requiring low privileges (PR:L), and no user interaction (UI:N). The impact is primarily on confidentiality (C:H), with no impact on integrity (I:N) or availability (A:L). The vulnerability does not currently have known exploits in the wild, but its presence in widely deployed chipsets makes it a significant concern. The flaw could be exploited by an attacker with local access to the device, such as through compromised applications or insider threats, to extract sensitive information from memory buffers. Qualcomm has not yet published patches, so mitigation currently relies on access control and monitoring. The vulnerability's broad presence in Snapdragon chipsets used in smartphones, IoT devices, and automotive systems increases the attack surface.

For European organizations, the primary impact of CVE-2025-47362 is the risk of sensitive information disclosure from devices running affected Snapdragon chipsets. This includes smartphones, tablets, IoT devices, and automotive systems widely used in enterprise and industrial environments. Confidential data leakage could lead to exposure of intellectual property, personal data, or security credentials, undermining privacy and compliance with regulations such as GDPR. The automotive sector, which increasingly relies on Snapdragon platforms for telematics and infotainment, could face risks to vehicle data confidentiality, potentially affecting safety and operational security. The local attack vector limits remote exploitation but insider threats or malware with local access could leverage this vulnerability. The medium severity rating suggests moderate urgency; however, the widespread deployment of affected devices in Europe amplifies the potential impact. Organizations in sectors like telecommunications, automotive manufacturing, and critical infrastructure should be particularly vigilant.

1. Monitor Qualcomm’s security advisories closely and apply official patches immediately upon release to address the buffer over-read flaw. 2. Restrict local access to devices with affected Snapdragon chipsets by enforcing strict access controls and endpoint security policies to prevent unauthorized local exploitation. 3. Employ application whitelisting and behavior monitoring to detect and block malicious software that could exploit this vulnerability locally. 4. For automotive systems, ensure secure firmware update mechanisms are in place to facilitate timely patch deployment. 5. Conduct regular security audits of devices running affected chipsets to identify unusual memory access patterns or data leakage indicators. 6. Collaborate with device manufacturers to verify the presence of patches and firmware updates in deployed hardware. 7. Educate users and administrators about the risks of local exploitation and the importance of device physical security. 8. Consider network segmentation to isolate critical systems using vulnerable devices, limiting lateral movement in case of compromise.
