CVE-2025-47348 is a vulnerability classified under CWE-457 (Use of Uninitialized Variable) found in Qualcomm Snapdragon platforms. The issue arises from improper initialization of variables during processing of identity credential operations within a trusted application environment, leading to memory corruption. Memory corruption vulnerabilities can cause unpredictable behavior, including crashes, privilege escalation, or arbitrary code execution. The affected Snapdragon products span a wide range of chipsets used in mobile devices, automotive platforms, IoT, and compute systems, including many Snapdragon 4G/5G mobile platforms, FastConnect wireless subsystems, and specialized Qualcomm platforms. The vulnerability requires local access with low privileges (PR:L) but does not require user interaction (UI:N), and the attack complexity is low (AC:L), making exploitation feasible for attackers with some access to the device. The CVSS v3.1 score of 7.8 reflects high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no public exploits are known yet, the broad product impact and critical nature of identity credential operations elevate the risk. The vulnerability could allow attackers to manipulate identity credentials, potentially bypassing security controls or gaining unauthorized access to sensitive data. Qualcomm has published the vulnerability but has not yet released patches, emphasizing the need for vigilance. The vulnerability affects devices globally, especially those relying on Snapdragon chipsets for secure identity and communication functions.

For European organizations, the impact of CVE-2025-47348 is significant due to the widespread use of Qualcomm Snapdragon chipsets in smartphones, automotive systems, IoT devices, and enterprise compute platforms. Exploitation could lead to unauthorized access to sensitive identity credentials, enabling data breaches, identity theft, or unauthorized system control. This could disrupt telecommunications infrastructure, compromise mobile workforce devices, and affect connected automotive or industrial systems. The high confidentiality, integrity, and availability impact means that critical business operations could be interrupted, leading to financial losses and reputational damage. Additionally, the vulnerability could be leveraged in targeted attacks against high-value targets such as government agencies, critical infrastructure operators, and large enterprises prevalent in Europe. The requirement for local access limits remote exploitation but does not eliminate risk, especially in environments where devices are physically accessible or compromised via other means. The lack of current exploits provides a window for mitigation but also underscores the urgency to patch and monitor affected systems.

1. Maintain an up-to-date inventory of all devices and systems using Qualcomm Snapdragon chipsets to identify affected assets accurately. 2. Monitor Qualcomm’s security advisories closely and apply official patches or firmware updates immediately upon release. 3. Implement strict access controls and endpoint security measures to limit local access to devices, including enforcing strong authentication and device lockdown policies. 4. Employ runtime protection and memory integrity monitoring tools on devices where feasible to detect anomalous behavior indicative of exploitation attempts. 5. For enterprise mobile devices, use Mobile Device Management (MDM) solutions to enforce security policies and remotely manage patch deployment. 6. In automotive and IoT environments, coordinate with device manufacturers and suppliers to ensure timely firmware updates and secure device configurations. 7. Conduct regular security audits and penetration testing focusing on local privilege escalation vectors to identify potential exploitation paths. 8. Educate users and administrators about the risks of local device compromise and the importance of physical security controls. 9. Consider network segmentation and isolation for critical devices to reduce the impact of a compromised endpoint. 10. Establish incident response plans that include scenarios involving memory corruption vulnerabilities and local privilege escalation.
