CVE-2025-47338 is a vulnerability classified under CWE-822 (Untrusted Pointer Dereference) found in Qualcomm Snapdragon components, specifically in the processing of escape commands originating from userspace. This flaw causes memory corruption due to improper handling of pointers that are not properly validated before dereferencing. The affected products include a wide range of Qualcomm chipsets such as FastConnect 6900 and 7800, QCC2072, SC8380XP, multiple WCD and WSA series chipsets, and several X and XG series variants. The vulnerability has a CVSS v3.1 score of 7.8, indicating high severity, with an attack vector of local access (AV:L), low attack complexity (AC:L), requiring low privileges (PR:L), and no user interaction (UI:N). The scope is unchanged (S:U), but the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). This means an attacker with local access and limited privileges can exploit this flaw to execute arbitrary code, escalate privileges, or cause denial of service by corrupting memory. The vulnerability was reserved in May 2025 and published in October 2025, with no known exploits in the wild yet. The lack of patches at the time of publication suggests that affected organizations must monitor Qualcomm advisories closely. The vulnerability is particularly dangerous because it involves escape commands, which are often used for low-level device control, increasing the risk of system compromise if exploited.

For European organizations, the impact of CVE-2025-47338 is significant due to the widespread use of Qualcomm Snapdragon chipsets in mobile devices, IoT devices, and embedded systems. Exploitation could lead to unauthorized access to sensitive data, disruption of critical services, and potential takeover of affected devices. This is especially critical for sectors relying on mobile communications and connected devices, such as telecommunications, manufacturing, healthcare, and public services. The high confidentiality, integrity, and availability impact means that data breaches, service outages, or device malfunctions could occur, potentially affecting business continuity and regulatory compliance under GDPR. The local access requirement limits remote exploitation but does not eliminate risk, as attackers could leverage social engineering or insider threats to gain initial access. The absence of known exploits currently provides a window for proactive defense, but the vulnerability's nature suggests it could be weaponized quickly once exploit code is developed.

1. Restrict local access to devices containing affected Qualcomm Snapdragon chipsets by enforcing strict physical and logical access controls, including endpoint security solutions and user privilege management. 2. Monitor system logs and device behavior for unusual escape command processing or memory corruption indicators, using advanced endpoint detection and response (EDR) tools. 3. Implement network segmentation to isolate critical devices and reduce the risk of lateral movement if a device is compromised. 4. Engage with Qualcomm and device vendors to obtain and apply security patches as soon as they become available; prioritize patch management for devices in sensitive environments. 5. Educate users and administrators about the risks of local exploitation and enforce policies to prevent unauthorized software installation or execution. 6. For organizations deploying IoT or embedded systems with affected chipsets, consider additional runtime protections such as memory protection mechanisms and integrity checks. 7. Conduct regular vulnerability assessments and penetration testing focusing on local privilege escalation vectors to identify potential exploitation paths.
