CVE-2025-46710 is a Use After Free (UAF) vulnerability classified under CWE-416, found in the Imagination Technologies Graphics Device Driver Kit (DDK), specifically version 1.15 RTM. This vulnerability arises from improper handling of kernel heap memory, where the driver attempts to read from or write to memory locations that have already been freed. Such behavior can lead to kernel exceptions, including crashes or undefined behavior, potentially allowing an attacker to execute arbitrary code with kernel privileges or cause denial of service (DoS) conditions. The vulnerability is located within the kernel-mode components of the Graphics DDK, which is responsible for managing graphics hardware resources and rendering operations. Since the flaw involves kernel heap memory, exploitation could compromise system stability and security by corrupting kernel memory structures or bypassing security controls. Although no known exploits are currently reported in the wild, the nature of UAF vulnerabilities makes them attractive targets for attackers seeking privilege escalation or system compromise. The absence of a patch at the time of publication increases the risk for systems running the affected version. The vulnerability does not require user interaction or authentication, as it resides in a kernel driver that may be accessible through local or possibly remote interfaces depending on the system configuration. The Graphics DDK is commonly integrated into embedded systems, mobile devices, and certain specialized computing environments that utilize Imagination Technologies’ GPU hardware and software stacks.

For European organizations, the impact of CVE-2025-46710 can be significant, especially for those relying on embedded systems, mobile devices, or specialized hardware that incorporate Imagination Technologies Graphics DDK version 1.15 RTM. Potential impacts include system instability, denial of service, and unauthorized privilege escalation leading to full system compromise. This could affect sectors such as telecommunications, automotive, industrial control systems, and consumer electronics manufacturers prevalent in Europe. Disruption of critical infrastructure or sensitive data exposure could result from exploitation. Given the kernel-level nature of the vulnerability, successful exploitation could undermine the confidentiality, integrity, and availability of affected systems. Organizations deploying devices with this Graphics DDK may face operational disruptions, increased incident response costs, and reputational damage. The lack of known exploits currently provides a window for proactive mitigation, but the vulnerability’s severity demands urgent attention to prevent future attacks.

1. Immediate inventory and identification of all devices and systems running Imagination Technologies Graphics DDK version 1.15 RTM within the organization. 2. Engage with Imagination Technologies and hardware vendors for updates or patches; prioritize deployment once available. 3. Implement strict access controls and limit exposure of affected devices to untrusted networks to reduce attack surface. 4. Employ kernel-level exploit mitigation techniques such as Kernel Address Space Layout Randomization (KASLR), Supervisor Mode Execution Prevention (SMEP), and Kernel Page-Table Isolation (KPTI) where supported. 5. Monitor system logs and kernel event traces for unusual behavior indicative of heap corruption or kernel exceptions. 6. For embedded and IoT devices, consider firmware updates or device replacement if patches are unavailable. 7. Conduct penetration testing and vulnerability scanning focused on kernel drivers to detect exploitation attempts. 8. Establish incident response procedures tailored to kernel-level compromises, including forensic readiness and recovery plans. 9. Educate development and security teams about the risks of use-after-free vulnerabilities and secure coding practices to prevent similar issues in future driver releases.
