CVE-2025-47376 is a use-after-free vulnerability classified under CWE-416 that affects numerous Qualcomm Snapdragon platforms and associated wireless connectivity components. The root cause is a memory corruption issue triggered by concurrent access to a shared buffer during IOCTL (Input/Output Control) calls, which are system calls used for device-specific operations. When multiple threads or processes access this shared buffer simultaneously without proper synchronization, it can lead to the buffer being freed while still in use, resulting in use-after-free conditions. This memory corruption can be exploited by an attacker with low-level privileges on the device to execute arbitrary code, escalate privileges, or cause a denial of service by crashing the affected component. The vulnerability spans a broad spectrum of Qualcomm products, including mobile platforms (e.g., Snapdragon 865, 888, 8 Gen 2), automotive platforms, wearable platforms, and various modem and wireless connectivity chips. The CVSS v3.1 base score is 7.8, reflecting high severity due to the potential for complete compromise of confidentiality, integrity, and availability. Exploitation requires local access with low privileges but does not require user interaction, increasing the risk in multi-user or shared device environments. No public exploits or active exploitation have been reported yet, but the extensive list of affected devices and platforms makes this a critical issue for Qualcomm device users and manufacturers. Qualcomm has not yet published patches at the time of this report, emphasizing the need for vigilance and proactive mitigation.

The impact of CVE-2025-47376 is significant for organizations and individuals using devices powered by affected Qualcomm Snapdragon platforms. Successful exploitation can lead to arbitrary code execution, allowing attackers to gain elevated privileges, access sensitive data, or disrupt device functionality. This can compromise the confidentiality, integrity, and availability of affected systems. In mobile devices, this could result in unauthorized access to personal data, interception of communications, or persistent malware installation. In automotive and IoT contexts, exploitation could disrupt critical systems, leading to safety risks or operational failures. The vulnerability's requirement for local access limits remote exploitation but does not eliminate risk in environments where attackers can gain physical or local network access, such as shared devices, corporate environments, or compromised applications. The broad range of affected platforms increases the attack surface globally, impacting industries relying on Qualcomm technology for mobile communications, automotive telematics, wearable devices, and industrial IoT. The absence of known exploits in the wild currently reduces immediate risk but does not preclude future attacks, especially as threat actors develop proof-of-concept exploits.

1. Restrict local access to devices using affected Qualcomm Snapdragon platforms by enforcing strict user permissions and limiting physical access. 2. Monitor system logs and IOCTL call patterns for unusual or concurrent access attempts that could indicate exploitation attempts. 3. Employ application whitelisting and sandboxing to reduce the risk of malicious code executing IOCTL calls. 4. Coordinate with device manufacturers and Qualcomm for timely receipt and deployment of security patches once available. 5. For organizations managing fleets of devices, implement automated patch management and vulnerability scanning focused on Qualcomm components. 6. Educate users about the risks of installing untrusted applications that could leverage local privileges to exploit this vulnerability. 7. In high-security environments, consider network segmentation and endpoint detection solutions to identify anomalous behavior related to this vulnerability. 8. Review and harden device configurations to minimize unnecessary IOCTL call exposure and shared buffer usage where possible.
