CVE-2025-47352 is a vulnerability classified under CWE-129 (Improper Validation of Array Index) found in Qualcomm Snapdragon chipsets, specifically affecting audio streaming operations. The flaw arises from insufficient validation of array indices, which leads to memory corruption during processing of audio data streams. This memory corruption can be exploited by an attacker with local privileges to execute arbitrary code, escalate privileges, or cause denial of service by crashing the affected component. The impacted products include FastConnect 7800, QCC2072, WCD9378C, WSA8840, WSA8845, WSA8845H, and several X-series modules, which are widely integrated into smartphones, tablets, and IoT devices. The vulnerability does not require user interaction but does require local access with low privileges, making it a significant threat in scenarios where an attacker gains limited access to the device. The CVSS v3.1 score of 7.8 indicates high severity with high impact on confidentiality, integrity, and availability, and low attack complexity. No patches have been published yet, and no known exploits are reported in the wild, but the potential for exploitation remains high given the critical nature of the flaw and the ubiquity of affected hardware. The vulnerability could allow attackers to compromise sensitive data, disrupt device functionality, or establish persistent footholds in affected devices.

For European organizations, the impact of CVE-2025-47352 is considerable due to the widespread use of Qualcomm Snapdragon chipsets in mobile devices and IoT infrastructure. Exploitation could lead to unauthorized access to sensitive corporate data, disruption of critical communications, and compromise of endpoint devices used by employees. This could affect sectors such as finance, healthcare, telecommunications, and government, where mobile and IoT device security is paramount. The memory corruption may result in device crashes or persistent malware installation, undermining operational continuity and data integrity. Given the local privilege requirement, insider threats or attackers who gain initial footholds through other means could leverage this vulnerability to escalate privileges and deepen their access. The absence of patches increases exposure time, raising the risk of targeted attacks. Additionally, the vulnerability could be leveraged in supply chain attacks or to compromise devices used in critical infrastructure, amplifying its impact across European digital ecosystems.

Organizations should implement a multi-layered mitigation strategy. First, maintain strict access controls and monitoring to prevent unauthorized local access to devices with affected Snapdragon chipsets. Employ endpoint detection and response (EDR) solutions to identify suspicious activities indicative of exploitation attempts. Since no patches are currently available, consider isolating or limiting the use of vulnerable devices in sensitive environments. Engage with device and chipset vendors to obtain timely updates and apply patches immediately upon release. Conduct thorough inventory and asset management to identify all devices using the affected Snapdragon components. Additionally, implement network segmentation to reduce the risk of lateral movement if a device is compromised. Educate users about the risks of local privilege escalation and enforce policies that minimize installation of untrusted applications or software. Finally, monitor threat intelligence sources for emerging exploit techniques targeting this vulnerability to adapt defenses proactively.
