CVE-2025-27059 is a vulnerability classified under CWE-823 (Use of Out-of-range Pointer Offset) affecting Qualcomm Snapdragon platforms. The flaw arises from improper handling of pointer offsets during Secure Channel Manager (SCM) calls, which are responsible for secure communication between different components of the chipset. This leads to memory corruption, potentially allowing an attacker to execute arbitrary code, escalate privileges, or cause denial of service. The affected Snapdragon platforms include a broad range of chipsets such as Immersive Home series (214, 216, 316, 318), IPQ series (IPQ5010, IPQ5028), QCN series (QCN6023 through QCN9274), which are commonly embedded in mobile devices, IoT gateways, and networking equipment. The vulnerability requires low privileges (PR:L) but no user interaction (UI:N), and has a scope change (S:C), meaning it can affect components beyond the initially compromised privilege level. The CVSS v3.1 score of 8.8 reflects high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no exploits are currently known in the wild, the vulnerability’s nature and affected platforms make it a significant risk for devices relying on these chipsets. The lack of available patches at the time of publication increases the urgency for mitigation and monitoring.

For European organizations, this vulnerability poses a significant risk especially for sectors relying on Qualcomm Snapdragon-based hardware, including telecommunications, IoT deployments, and embedded systems in critical infrastructure. Exploitation could lead to unauthorized access to sensitive data, manipulation or disruption of device functions, and potential lateral movement within networks. The high severity and scope change imply that an attacker could compromise the underlying hardware security, undermining trust in device integrity and availability. This could impact mobile network operators, smart city deployments, industrial control systems, and consumer devices prevalent in Europe. The disruption or compromise of such devices could lead to service outages, data breaches, and operational disruptions, with cascading effects on business continuity and regulatory compliance under GDPR and NIS Directive frameworks.

1. Monitor Qualcomm’s security advisories closely and apply patches immediately once released for the affected Snapdragon platforms. 2. Restrict access to SCM interfaces and related privileged components to trusted processes and users only, using strict access control policies. 3. Employ runtime integrity monitoring and anomaly detection on devices to identify unusual memory access patterns or SCM call behaviors indicative of exploitation attempts. 4. Segment networks to isolate vulnerable devices and limit potential lateral movement in case of compromise. 5. For embedded and IoT devices, ensure secure boot and firmware validation mechanisms are enabled to prevent unauthorized code execution. 6. Collaborate with device vendors to confirm patch availability and deployment timelines. 7. Conduct regular security assessments and penetration testing focusing on hardware and firmware layers to detect similar memory corruption issues.
