CVE-2025-47341 is a classic buffer overflow vulnerability (CWE-120) identified in Qualcomm Snapdragon and associated platforms, including FastConnect modules, compute platforms, and audio components. The flaw occurs during the processing of an image encoding completion event, where the software fails to properly check the size of input data before copying it into a buffer. This unchecked buffer copy leads to memory corruption, which can be exploited by an attacker with local access and low privileges to execute arbitrary code or cause denial of service. The vulnerability affects a wide array of Qualcomm products such as FastConnect 6700/6900/7800, Snapdragon 7c+ Gen 3 Compute, Snapdragon 8cx Gen 3 Compute, and various WCD and WSA audio components. The CVSS v3.1 score is 7.8 (high), reflecting the vulnerability's significant impact on confidentiality, integrity, and availability, combined with relatively low attack complexity and no requirement for user interaction. While no public exploits are currently known, the broad product impact and potential for privilege escalation or system compromise make this a critical issue for device manufacturers and users. The vulnerability was reserved in May 2025 and published in October 2025, with no patches currently linked, indicating that mitigation efforts are likely ongoing.

The vulnerability poses a serious risk to European organizations relying on Qualcomm Snapdragon-based devices, including smartphones, tablets, IoT devices, and embedded compute platforms. Exploitation could allow attackers to execute arbitrary code locally, potentially leading to data breaches, unauthorized access to sensitive information, or disruption of critical services. Telecommunications providers, enterprises using mobile computing platforms, and industries deploying IoT devices with affected chipsets could face operational disruptions or compromise of confidential data. Given the widespread use of Qualcomm Snapdragon technology in consumer and enterprise devices across Europe, the scope of impact is extensive. Additionally, compromised devices could be leveraged as entry points for lateral movement within corporate networks, increasing the overall risk posture. The absence of known exploits in the wild provides a window for proactive mitigation, but the high severity necessitates urgent attention.

1. Monitor Qualcomm’s official channels for patches addressing CVE-2025-47341 and apply them promptly once available. 2. Implement strict access controls to limit local access to devices running affected Snapdragon platforms, reducing the attack surface. 3. Employ runtime protections such as Address Space Layout Randomization (ASLR) and Data Execution Prevention (DEP) where supported by the device OS to mitigate exploitation attempts. 4. Conduct thorough security audits of image processing components and related services to detect anomalous behavior indicative of exploitation attempts. 5. For organizations deploying IoT or embedded devices, ensure firmware is updatable and establish processes for rapid patch deployment. 6. Network segmentation can help contain potential breaches originating from compromised devices. 7. Educate users and administrators about the risks of local privilege escalation vulnerabilities and enforce policies to minimize installation of untrusted software that could trigger the vulnerability.
