CVE-2025-46708: CWE - CWE-280: Improper Handling of Insufficient Permissions or Privileges (4.15) in Imagination Technologies Graphics DDK
Software installed and running inside a Guest VM may conduct improper GPU system calls to prevent other Guests from running work on the GPU.
AI Analysis
Technical Summary
CVE-2025-46708 is a vulnerability identified in the Imagination Technologies Graphics Device Driver Kit (DDK), specifically affecting versions 1.15 RTM, 1.17 RTM, 1.18 RTM, and 23.2 RTM. The core issue relates to improper handling of insufficient permissions or privileges (CWE-280) within the GPU virtualization environment. In this scenario, software running inside a guest virtual machine (VM) can exploit improper GPU system call handling to interfere with the GPU resource allocation and scheduling. This allows a malicious or compromised guest VM to prevent other guest VMs from executing their GPU workloads effectively, leading to a denial of service (DoS) condition on the GPU resources. The vulnerability arises because the Graphics DDK does not adequately enforce permission checks or privilege boundaries when processing GPU system calls from guest VMs. Consequently, a guest VM can issue system calls that disrupt or monopolize GPU scheduling, impacting the availability of GPU resources for other guests. This is particularly critical in multi-tenant environments such as cloud infrastructure or virtualized data centers where GPU sharing is common. The vulnerability does not appear to allow direct data leakage or privilege escalation beyond the guest VM boundary, but it can cause significant disruption by degrading or denying GPU access to other tenants. No known exploits are currently reported in the wild, and no CVSS score has been assigned yet. However, the vulnerability is publicly disclosed and should be addressed promptly to maintain secure GPU virtualization operations.
Potential Impact
For European organizations, especially those relying on virtualized GPU resources for cloud computing, AI workloads, or graphical processing in multi-tenant environments, this vulnerability poses a risk of service disruption. Organizations using Imagination Technologies Graphics DDK in their virtualization stacks may experience denial of service on GPU resources, which can degrade performance or halt critical workloads. This can impact sectors such as research institutions, financial services, media production, and any industry leveraging GPU acceleration in virtualized environments. The inability to isolate GPU usage among guest VMs undermines the reliability and availability of shared GPU infrastructure, potentially leading to operational downtime and loss of productivity. While confidentiality and integrity impacts appear limited, the availability impact is significant. This could also affect cloud service providers operating in Europe who offer GPU-accelerated virtual machines, potentially affecting their service level agreements (SLAs) and customer trust.
Mitigation Recommendations
Since no patches are currently linked, European organizations should take immediate steps to mitigate the risk. First, they should audit their virtualization environments to identify the use of affected versions of the Imagination Technologies Graphics DDK. Where possible, isolate GPU resources to dedicated VMs or physical hosts to reduce multi-tenant exposure. Implement strict access controls and monitoring on GPU system calls and virtualization management interfaces to detect anomalous GPU usage patterns indicative of exploitation attempts. Consider disabling GPU sharing features temporarily if feasible until a vendor patch or update is released. Engage with Imagination Technologies for updates on patches or mitigations and plan for timely deployment once available. Additionally, organizations should review their incident response plans to include scenarios involving GPU resource denial and ensure logging and alerting are configured to capture relevant GPU virtualization events. For cloud providers, offering customers transparency about affected hardware and potential impacts is advisable.
