CVE-2025-47359 is a use-after-free vulnerability classified under CWE-416 that affects a wide range of Qualcomm Snapdragon products, including various FastConnect modules, Snapdragon compute platforms (8c, 8cx generations), and wireless audio components (WCD and WSA series). The root cause is a race condition where multiple threads concurrently invoke a memory free API, leading to memory corruption. This can result in the use of freed memory, which attackers with local privileges could exploit to execute arbitrary code, escalate privileges, or cause denial of service by crashing the system. The vulnerability has a CVSS 3.1 base score of 7.8, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity and requiring low privileges but no user interaction. The flaw affects both mobile and compute platforms, which are widely deployed in smartphones, laptops, and IoT devices. Although no public exploits are known yet, the vulnerability's nature and affected components make it a critical concern for device manufacturers and end users. Qualcomm has not yet published patches, emphasizing the need for vigilance and proactive mitigation. The vulnerability's exploitation could compromise sensitive data, disrupt communications, and undermine device trustworthiness.

For European organizations, this vulnerability poses a significant risk due to the widespread use of Qualcomm Snapdragon chipsets in mobile devices, laptops, and embedded systems. Confidentiality could be breached if attackers gain code execution capabilities, potentially exposing sensitive corporate or personal data. Integrity and availability are also at risk, as exploitation could allow attackers to modify system behavior or cause device crashes, disrupting business operations. Sectors such as finance, healthcare, and critical infrastructure that rely heavily on mobile and wireless technology could face operational disruptions and data breaches. The requirement for local privileges limits remote exploitation but insider threats or malware already present on devices could leverage this vulnerability to escalate privileges or persist undetected. The lack of current public exploits provides a window for mitigation, but the broad device impact and potential for future exploit development necessitate urgent attention.

Organizations should monitor Qualcomm and device manufacturers for official patches and apply them promptly once available. Until patches are released, implementing strict access controls to limit local user privileges can reduce exploitation risk. Employing endpoint detection and response (EDR) solutions to monitor for suspicious memory corruption or unusual thread activity can help detect exploitation attempts. Developers and OEMs should review and improve thread synchronization and memory management in affected components to prevent concurrent access issues. Network segmentation and device usage policies can limit exposure of vulnerable devices in sensitive environments. Regular security audits and penetration testing focusing on local privilege escalation vectors can identify potential exploitation paths. Additionally, educating users about the risks of installing untrusted applications that could exploit local vulnerabilities is important. Finally, consider deploying runtime protections such as Control Flow Integrity (CFI) and Address Space Layout Randomization (ASLR) to mitigate exploitation impact.
