CVE-2025-47379 is a use-after-free vulnerability classified under CWE-416 that affects a wide array of Qualcomm Snapdragon platforms and associated products, including mobile platforms, automotive modems, wireless access platforms, and IoT devices. The root cause is improper synchronization between the assignment and deallocation of shared buffer resources during concurrent access, which leads to memory corruption. This flaw can be exploited locally by an attacker with limited privileges (PR:L) without requiring user interaction (UI:N). The vulnerability impacts confidentiality, integrity, and availability (C:H/I:H/A:H) of the affected systems, as attackers may execute arbitrary code, escalate privileges, or cause system crashes and denial of service. The CVSS v3.1 score is 7.8, indicating a high severity level. The affected product list is extensive, covering numerous Snapdragon mobile platforms (e.g., Snapdragon 865, 888, 8 Gen 2/3), FastConnect wireless modules, automotive platforms, and other Qualcomm chipsets. Although no known exploits are reported in the wild yet, the vulnerability's nature and broad impact make it a critical concern. The lack of available patches at the time of publication necessitates immediate risk mitigation efforts. Qualcomm’s Snapdragon platforms are widely deployed globally in smartphones, automotive systems, and wireless infrastructure, making this vulnerability a significant threat vector for many organizations and end-users.

The impact of CVE-2025-47379 is substantial due to the widespread use of affected Qualcomm Snapdragon platforms across multiple sectors including mobile devices, automotive systems, IoT, and wireless infrastructure. Successful exploitation can lead to arbitrary code execution, allowing attackers to gain elevated privileges and potentially take full control of the device. This compromises confidentiality by exposing sensitive data, integrity by allowing unauthorized modifications, and availability by causing crashes or denial of service. The vulnerability’s requirement for local privilege means attackers must have some level of access to the device, but once exploited, the damage can be severe. Organizations relying on these platforms for critical communications, automotive safety, or industrial IoT may face operational disruptions, data breaches, or safety risks. The broad product impact increases the attack surface, affecting millions of devices worldwide. The absence of known exploits currently provides a window for proactive defense, but the risk of future exploitation remains high given the vulnerability’s severity and scope.

1. Monitor Qualcomm’s official security advisories closely and apply patches or firmware updates as soon as they become available for affected Snapdragon platforms. 2. Implement strict access controls and privilege separation on devices using these platforms to limit local user capabilities and reduce the risk of exploitation. 3. Employ runtime protections such as memory corruption mitigations (e.g., ASLR, DEP) and sandboxing to contain potential exploitation impacts. 4. Conduct thorough code audits and testing for concurrent buffer access in custom or third-party software interfacing with Qualcomm hardware to identify and remediate synchronization issues. 5. Use endpoint detection and response (EDR) solutions to monitor for anomalous behavior indicative of exploitation attempts, such as unusual memory access patterns or crashes. 6. For organizations deploying these platforms in automotive or critical infrastructure, implement layered security controls including network segmentation and strict update management to reduce attack vectors. 7. Educate internal security teams and device users about the risks and signs of exploitation to enable rapid detection and response. 8. Where possible, restrict physical and local access to devices to trusted personnel only, minimizing opportunities for local attackers to exploit the vulnerability.
