CVE-2025-47340 is an out-of-bounds write vulnerability classified under CWE-787, discovered in Qualcomm Snapdragon components including FastConnect 6900, 7800, and various chipsets such as QCC2072 and SC8380XP. The vulnerability arises from improper memory handling during the processing of a specific IOCTL call used to retrieve mapping information. An attacker with low privileges (PR:L) and no user interaction (UI:N) can exploit this flaw locally (AV:L) to corrupt memory, which can lead to arbitrary code execution or system crashes. The vulnerability impacts confidentiality, integrity, and availability (C:H/I:H/A:H) of the affected devices. Snapdragon chipsets are widely used in mobile phones, IoT devices, and embedded systems, making this a critical issue for device security. No public exploits have been reported yet, but the vulnerability's nature and CVSS score of 7.8 indicate a high risk. The lack of available patches at the time of publication necessitates immediate attention from vendors and users to monitor updates and apply fixes once available.

For European organizations, the impact of CVE-2025-47340 is significant due to the widespread use of Qualcomm Snapdragon chipsets in smartphones, IoT devices, and embedded systems integral to business operations and critical infrastructure. Exploitation could lead to unauthorized access to sensitive data, disruption of services, and potential device takeover, affecting confidentiality, integrity, and availability. Industries such as telecommunications, manufacturing, healthcare, and finance that rely heavily on mobile and IoT technologies are particularly vulnerable. The vulnerability could also facilitate lateral movement within networks if exploited on corporate devices, increasing the risk of broader compromises. Given the local attack vector, insider threats or malware with limited privileges could leverage this flaw to escalate privileges or execute arbitrary code, amplifying the threat landscape for European enterprises.

1. Coordinate with device manufacturers and Qualcomm to obtain and deploy security patches as soon as they become available. 2. Restrict access to IOCTL interfaces on affected devices by enforcing strict access control policies and limiting device usage to trusted users and applications. 3. Implement endpoint detection and response (EDR) solutions capable of monitoring anomalous IOCTL calls or memory corruption indicators. 4. Conduct regular security audits and vulnerability assessments on devices using affected Snapdragon components to identify potential exploitation attempts. 5. Employ network segmentation to isolate critical systems and reduce the attack surface in case of device compromise. 6. Educate users and administrators about the risks associated with local privilege escalation vulnerabilities and encourage prompt reporting of suspicious device behavior. 7. Monitor threat intelligence feeds for emerging exploit techniques targeting this vulnerability to adapt defenses proactively.
