CVE-2025-47360 is a stack-based buffer overflow vulnerability classified under CWE-121, found in Qualcomm Snapdragon chipsets during the processing of client messages in device management components. This vulnerability results from improper handling of memory buffers, leading to memory corruption. The affected Snapdragon versions include a broad range of models such as QAM8255P, SA8150P, and SRV1M, covering many devices in the mobile and embedded markets. The vulnerability has a CVSS 3.1 base score of 7.8, indicating high severity, with an attack vector requiring local access (AV:L), low attack complexity (AC:L), low privileges (PR:L), and no user interaction (UI:N). The impact on confidentiality, integrity, and availability is high, meaning successful exploitation could allow an attacker to execute arbitrary code, escalate privileges, or cause denial of service. Although no exploits are currently known in the wild, the vulnerability's nature and affected platforms make it a significant risk. The flaw lies in the device management message processing code, which when fed crafted input, can overflow stack buffers and corrupt memory, potentially leading to control flow hijacking. Qualcomm has not yet published patches, so mitigation currently relies on limiting local access and monitoring. The vulnerability affects devices globally, but its impact is particularly relevant to environments where Snapdragon chipsets are prevalent.

For European organizations, the impact of CVE-2025-47360 can be substantial, especially those relying on mobile devices, IoT, or embedded systems powered by affected Qualcomm Snapdragon chipsets. Exploitation could lead to unauthorized code execution, data leakage, device manipulation, or denial of service, undermining operational continuity and data security. Critical sectors such as telecommunications, finance, healthcare, and government agencies using Snapdragon-based devices could face increased risk of targeted attacks or lateral movement within networks. The requirement for local access limits remote exploitation but does not eliminate risk, as attackers could leverage social engineering or physical access to exploit the vulnerability. The broad range of affected Snapdragon models means many consumer and enterprise devices in Europe are potentially vulnerable, raising concerns about supply chain security and device integrity. The absence of known exploits provides a window for proactive defense, but the high severity score underscores the urgency for mitigation.

1. Monitor Qualcomm’s security advisories closely and apply official patches immediately upon release to remediate the vulnerability. 2. Implement strict access controls to limit local access to devices running affected Snapdragon chipsets, including enforcing strong authentication and physical security measures. 3. Employ endpoint detection and response (EDR) solutions capable of identifying anomalous behavior indicative of buffer overflow exploitation attempts. 4. Conduct regular device inventory and firmware audits to identify devices with vulnerable Snapdragon versions and prioritize their remediation. 5. For organizations deploying embedded systems or IoT devices with affected chipsets, consider network segmentation to contain potential compromises. 6. Educate users and administrators about the risks of local privilege escalation vulnerabilities and the importance of device security hygiene. 7. Collaborate with device manufacturers and suppliers to ensure timely firmware updates and security patches are integrated into device management workflows. 8. Where patching is delayed, consider deploying compensating controls such as application whitelisting and restricting installation of untrusted software to reduce exploitation likelihood.
