CVE-2025-47380 is a vulnerability classified under CWE-822 (Untrusted Pointer Dereference) affecting Qualcomm Snapdragon components, specifically during the preprocessing of IOCTL (Input/Output Control) commands in sensor subsystems. This flaw results in memory corruption, which can be exploited by an attacker with low privileges (PR:L) and no user interaction (UI:N). The vulnerability impacts a range of Snapdragon products including FastConnect 7800, QCC2072, WCD9378C, WSA8840 series, and multiple X-series chipsets. The memory corruption arises because the sensor IOCTL handler improperly dereferences pointers without sufficient validation, allowing crafted IOCTL requests to manipulate memory arbitrarily. This can lead to arbitrary code execution, privilege escalation, or denial of service by corrupting kernel or driver memory. The CVSS v3.1 base score is 7.8, indicating high severity with high impact on confidentiality, integrity, and availability. The attack vector is local (AV:L), meaning an attacker needs local access to the device but only low privileges (PR:L) and no user interaction. No public exploits are known yet, but the vulnerability’s nature and affected widespread Snapdragon components make it a significant threat. The lack of available patches at publication time necessitates immediate risk mitigation and monitoring. Qualcomm’s sensor drivers are embedded in many mobile and IoT devices, making this vulnerability relevant for a broad ecosystem.

For European organizations, the impact of CVE-2025-47380 is substantial due to the widespread use of Qualcomm Snapdragon chips in smartphones, IoT devices, and embedded systems. Exploitation could allow attackers to gain unauthorized access to sensitive data, manipulate device behavior, or cause service disruptions. Telecommunications providers, mobile device manufacturers, and enterprises deploying IoT infrastructure are particularly at risk. Compromise of devices could lead to data breaches, espionage, or disruption of critical services. The vulnerability’s local attack vector implies that attackers need some form of access, such as physical access or compromised user accounts, but the low privilege requirement lowers the barrier. Given the high confidentiality, integrity, and availability impact, successful exploitation could undermine trust in mobile communications and connected infrastructure. This is critical for sectors like finance, healthcare, and government in Europe where data protection and service continuity are paramount. The absence of known exploits currently provides a window for proactive defense, but the potential for rapid weaponization exists.

1. Monitor Qualcomm and device vendors for official patches and apply them promptly once released. 2. Restrict access to IOCTL interfaces related to sensor drivers using strict access control policies and sandboxing to limit local attacker capabilities. 3. Employ device integrity verification and runtime protection mechanisms to detect anomalous memory corruption or unauthorized code execution attempts. 4. Harden endpoint security by limiting local user privileges and disabling unnecessary services that could be leveraged to trigger IOCTL calls. 5. Implement network segmentation and strong authentication to reduce the risk of attackers gaining local access to vulnerable devices. 6. Use endpoint detection and response (EDR) tools to monitor for suspicious activity related to sensor drivers or kernel memory anomalies. 7. Educate users and administrators about the risks of local privilege escalation vulnerabilities and the importance of device security hygiene. 8. For IoT deployments, consider network-level protections and device isolation to contain potential exploitation impacts.
