CVE-2025-27069 is a high-severity vulnerability identified in several Qualcomm Snapdragon components, specifically affecting FastConnect 6900, FastConnect 7800, SC8380XP, WCD9380, WCD9385, WSA8840, WSA8845, and WSA8845H chipsets. The vulnerability is classified under CWE-822, which pertains to untrusted pointer dereference, a type of memory corruption issue. This flaw arises during the processing of DDI (Device Driver Interface) command calls, where an attacker with limited privileges (PR:L) can cause the system to dereference pointers that have not been properly validated or sanitized. The CVSS 3.1 base score of 7.8 reflects the high impact on confidentiality, integrity, and availability (all rated high), with low attack complexity and no user interaction required. The attack vector is local, meaning the attacker needs some level of access to the device but does not require user interaction to exploit the vulnerability. Exploiting this flaw could lead to arbitrary code execution, privilege escalation, or system crashes, potentially compromising the affected device's security and stability. Qualcomm Snapdragon chipsets are widely used in mobile devices, embedded systems, and IoT devices, making this vulnerability particularly relevant for environments relying on these platforms. Although no known exploits are currently reported in the wild, the severity and nature of the vulnerability warrant prompt attention and remediation once patches become available.

For European organizations, the impact of CVE-2025-27069 could be significant, especially for those relying on mobile devices, embedded systems, or IoT infrastructure powered by affected Qualcomm Snapdragon chipsets. Confidentiality breaches could expose sensitive corporate or personal data, while integrity compromises might allow attackers to manipulate device operations or firmware. Availability impacts could disrupt critical business communications or operational technology systems. Sectors such as telecommunications, finance, healthcare, and government agencies that utilize Snapdragon-based devices for secure communications or operational control could face increased risk. Additionally, the local attack vector implies that insider threats or attackers who gain initial access to devices could leverage this vulnerability to escalate privileges or move laterally within networks. The absence of user interaction in exploitation further increases the risk of stealthy attacks. Given the widespread use of Qualcomm Snapdragon in smartphones and embedded devices, this vulnerability could also affect remote workforces and mobile employees, potentially expanding the attack surface for European enterprises.

To mitigate CVE-2025-27069, European organizations should: 1) Monitor Qualcomm and device vendors for official patches or firmware updates addressing this vulnerability and prioritize their deployment across all affected devices. 2) Implement strict access controls and endpoint security measures to limit local access to devices, reducing the risk of exploitation by unauthorized users. 3) Employ device management solutions to inventory and track devices using affected Snapdragon chipsets, enabling targeted remediation efforts. 4) Restrict installation of untrusted applications and enforce application whitelisting policies to prevent malicious code execution that could leverage this vulnerability. 5) Enhance network segmentation to isolate critical systems and reduce lateral movement opportunities in case of compromise. 6) Conduct regular security audits and penetration testing focusing on mobile and embedded device security to identify potential exploitation paths. 7) Educate users and administrators about the risks associated with local privilege escalation vulnerabilities and the importance of timely updates. Since no patches are currently available, organizations should also consider temporary compensating controls such as disabling unnecessary services or interfaces that process DDI commands if feasible.
