CVE-2025-47348 is a vulnerability classified under CWE-457 (Use of Uninitialized Variable) found in Qualcomm Snapdragon platforms. The flaw arises from improper initialization of variables during processing of identity credential operations within a trusted application environment. This leads to memory corruption, which can be exploited to compromise the confidentiality, integrity, and availability of the affected system. The vulnerability affects a vast array of Qualcomm products including numerous Snapdragon mobile platforms (from Snapdragon 4 Gen 1 up to Snapdragon 8 Gen 3), FastConnect wireless subsystems, various modem-RF systems, compute platforms, automotive platforms, and audio platforms. The CVSS v3.1 score is 7.8 (high severity), with an attack vector of local access (AV:L), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), and impacting confidentiality, integrity, and availability (C:H/I:H/A:H). Exploitation requires local privileged access, indicating that an attacker must already have some level of control or access to the device. The vulnerability could allow attackers to execute arbitrary code, leak sensitive identity credentials, or cause denial of service by corrupting memory. No public patches or exploits are currently known, but the broad product impact and critical nature of identity credential handling make this a significant threat. The vulnerability was reserved in May 2025 and published in January 2026, indicating recent discovery and disclosure.

For European organizations, the impact of CVE-2025-47348 is substantial due to the widespread use of Qualcomm Snapdragon chipsets in mobile devices, IoT devices, automotive systems, and enterprise compute platforms. Confidentiality breaches could expose sensitive identity credentials, leading to identity theft or unauthorized access to corporate networks. Integrity violations might allow attackers to manipulate device operations or firmware, potentially undermining security controls or enabling persistent threats. Availability impacts could disrupt critical services, especially in sectors relying on connected devices such as automotive, healthcare, and industrial control systems. Given the vulnerability requires local privileged access, insider threats or malware already present on devices could escalate their capabilities. The broad product range affected means many devices in use across Europe could be vulnerable, increasing the attack surface. This is particularly concerning for organizations with Bring Your Own Device (BYOD) policies or those deploying Snapdragon-based IoT and automotive solutions. The lack of known exploits currently provides a window for mitigation, but the high severity score demands urgent attention to prevent future exploitation.

Mitigation should focus on a multi-layered approach: 1) Immediate coordination with device manufacturers and vendors to obtain and apply firmware and software updates addressing this vulnerability once available. 2) Implement strict access controls and monitoring on devices with Qualcomm Snapdragon components to prevent unauthorized local access or privilege escalation. 3) Employ endpoint detection and response (EDR) solutions capable of detecting anomalous behavior indicative of memory corruption or exploitation attempts. 4) Enforce strong identity and credential management policies to limit the impact of credential compromise. 5) Conduct regular security audits and penetration testing on devices and applications using affected platforms to identify potential exploitation paths. 6) For organizations deploying IoT or automotive systems, ensure network segmentation and isolation to contain potential breaches. 7) Educate users and administrators about the risks of local privilege escalation and the importance of applying updates promptly. 8) Monitor threat intelligence feeds for any emerging exploits or patches related to CVE-2025-47348 to respond swiftly.
