CVE-2025-27046 is a high-severity vulnerability identified in multiple Qualcomm Snapdragon platforms and associated components, characterized as a CWE-415 Double Free flaw. This vulnerability arises due to improper memory management when processing multiple simultaneous escape calls, leading to memory corruption. A double free occurs when the same memory location is freed more than once, which can corrupt the heap and potentially allow an attacker to execute arbitrary code, cause denial of service, or escalate privileges. The affected products include a broad range of Snapdragon SoCs (System on Chips) such as the Snapdragon 7c, 8c, and 8cx compute platforms, FastConnect wireless subsystems (6200 through 7800 series), various Qualcomm Wi-Fi and audio components (QCA, QCM, QCS series, WCD and WSA series), and the Qualcomm Video Collaboration VC3 Platform. The CVSS v3.1 base score is 7.8, indicating a high severity level, with the vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. This means the attack requires local access with low complexity and low privileges, no user interaction is needed, and the impact on confidentiality, integrity, and availability is high. No known exploits are currently reported in the wild, and no patches are linked yet, suggesting that affected organizations should prioritize monitoring and mitigation. The vulnerability's exploitation could allow attackers with local access to cause significant damage, including full system compromise on devices using these Qualcomm components.

For European organizations, the impact of CVE-2025-27046 is substantial, especially those relying on devices and infrastructure powered by Qualcomm Snapdragon platforms. This includes mobile devices, laptops, IoT devices, and wireless communication modules prevalent in enterprise environments. The vulnerability could lead to unauthorized code execution, data breaches, or service disruptions, compromising sensitive corporate data and critical communications. Given the widespread use of Qualcomm Snapdragon chips in consumer and enterprise-grade hardware, the risk extends to sectors such as telecommunications, finance, healthcare, and government agencies. The local attack vector implies that threat actors would need some form of local access, which could be achieved through physical access, compromised user accounts, or malware footholds. The high impact on confidentiality, integrity, and availability means that successful exploitation could disrupt business operations, leak sensitive information, and undermine trust in critical systems. Additionally, the lack of available patches increases the window of exposure, necessitating immediate risk management and mitigation efforts.

European organizations should implement a multi-layered mitigation strategy beyond generic patching advice. First, conduct an inventory of all devices and systems using affected Qualcomm Snapdragon platforms, including embedded IoT devices and wireless modules. Restrict local access to these devices by enforcing strict physical security controls and limiting user privileges to the minimum necessary. Deploy endpoint detection and response (EDR) solutions capable of identifying anomalous memory corruption behaviors or suspicious escape call patterns. Network segmentation should be employed to isolate vulnerable devices from critical infrastructure and sensitive data repositories. Organizations should also monitor for unusual local activity indicative of exploitation attempts, such as unexpected process crashes or memory errors. Until official patches are released, consider deploying virtual patching techniques or application whitelisting to prevent unauthorized code execution. Engage with device vendors and Qualcomm for timely updates and apply firmware or software patches as soon as they become available. Additionally, educate IT and security staff about this vulnerability to enhance incident response readiness.
