CVE-2025-47388 is a classic buffer overflow vulnerability (CWE-120) identified in various Qualcomm Snapdragon and related platforms. The flaw arises due to improper handling of memory when passing pages to the Digital Signal Processor (DSP) with an unaligned starting address, leading to memory corruption. This vulnerability affects a broad spectrum of Qualcomm products, including FastConnect wireless connectivity modules (6200, 6700, 6900, 7800), multiple Snapdragon mobile platforms (4 Gen 2, 6 Gen 1), wearable platforms (W5+ Gen 1), and various wireless communication chips (WCD, WCN, WSA series). The CVSS v3.1 score of 7.8 reflects a high severity, with an attack vector requiring local access (AV:L), low complexity (AC:L), low privileges (PR:L), no user interaction (UI:N), and impacts on confidentiality, integrity, and availability (C:H/I:H/A:H). The vulnerability allows an attacker with limited privileges to exploit the buffer overflow by providing unaligned memory addresses to the DSP, potentially leading to arbitrary code execution, privilege escalation, or system crashes. While no exploits are currently known in the wild, the vulnerability's nature and affected components pose a significant risk to devices relying on these chipsets. The lack of available patches at the time of publication necessitates proactive mitigation and monitoring. This vulnerability is particularly critical because it affects core hardware components embedded in many consumer and enterprise devices, including smartphones, wearables, and IoT devices, which are prevalent in European markets.

For European organizations, the impact of CVE-2025-47388 could be substantial. Devices using affected Qualcomm Snapdragon and related platforms are widespread across consumer electronics, enterprise mobile devices, and IoT deployments. Exploitation could lead to unauthorized access to sensitive data, disruption of device operations, and potential lateral movement within corporate networks. The high confidentiality, integrity, and availability impact means attackers could exfiltrate data, implant persistent malware, or cause denial-of-service conditions. Critical sectors such as finance, healthcare, telecommunications, and government agencies that rely on mobile and embedded devices with these chipsets are at heightened risk. Additionally, the vulnerability could undermine trust in mobile communications and wearable health devices, impacting compliance with European data protection regulations like GDPR. The local attack vector implies that physical or local network access is required, which may limit remote exploitation but does not eliminate risk in environments where devices are shared or accessible. The broad range of affected products increases the attack surface, making comprehensive asset inventory and patch management essential.

Organizations should immediately identify all devices using affected Qualcomm Snapdragon and related platforms through asset management and inventory tools. Since no official patches are available at the time of publication, organizations should monitor Qualcomm advisories and vendor updates closely to apply patches promptly once released. In the interim, restrict local access to devices, enforce strict physical security controls, and limit user privileges to reduce the risk of exploitation. Employ endpoint detection and response (EDR) solutions capable of detecting anomalous behavior indicative of memory corruption or privilege escalation attempts. Network segmentation can help contain potential compromises. For device manufacturers and integrators, implementing rigorous input validation and memory alignment checks in firmware and driver code is critical. Additionally, consider deploying runtime protections such as Control Flow Integrity (CFI) and Address Space Layout Randomization (ASLR) where supported. Regularly update device firmware and operating systems to incorporate security improvements. Finally, educate users about the risks of installing untrusted applications or connecting to untrusted networks, which could facilitate local exploitation.
