Ddk

Local privilege escalation in Imagination Technologies Graphics DDK allows low-privileged users to corrupt kernel memory and driver data structures through malicious GPU system calls. The vulnerability affects DDK versions 1.18 RTM, 23.2 RTM, 24.1-24.2 RTM, and 25.1-25.3 RTM. Attackers with local access can force the GPU to write to arbitrary physical memory pages, including restricted internal GPU buffers and kernel memory regions, achieving complete system compromise (CVSS 7.8). EPSS data not available; no active exploitation confirmed per CISA SSVC framework (exploitation status: none), but the local attack vector and total technical impact make this critical for systems with untrusted local users.

Use-after-free in Imagination Graphics DDK GPU GLES user-space library allows authenticated remote attackers to crash the GPU render process via crafted WebGPU content. CVSS 8.1 (High) with network vector and low complexity. On platforms where the GPU process runs with elevated system privileges, successful exploitation could enable system-level compromise beyond the initial crash. EPSS and KEV data not provided; SSVC framework indicates no confirmed exploitation, non-automatable attack, but total technical impact. Vendor patches available across affected DDK versions 1.18, 23.2, 24.1-24.2, and 25.1-25.3.

Remote authenticated attackers can execute code or cause persistent denial-of-service in Imagination Technologies Graphics DDK by triggering a use-after-free in the GPU GLES render process via specially crafted WebGPU content. On platforms where the GPU driver runs with elevated system privileges, successful exploitation enables device-level compromise beyond the browser sandbox. EPSS data not available, no CISA KEV listing identified, no public POC confirmed. SSVC framework indicates no active exploitation and non-automatable attack requiring authenticated interaction.

Improper GPU system call handling in the DDK allows non-privileged users to bypass memory protections on user-mode wrapped memory regions and gain unauthorized write access. An attacker with local access could exploit this to modify read-only memory structures, potentially compromising system integrity or escalating privileges. No patch is currently available for this medium-severity vulnerability.

Write-after-free crash in GPU compiler process triggered by unusual GPU shader code loaded from the web. Browser vulnerability through WebGPU shader compilation.

Software installed and run as a non-privileged user may conduct improper GPU system calls to cause mismanagement of reference counting to cause a potential use after free. Improper reference counting on an internal resource caused scenario where potential for use after free was present. [CVSS 7.8 HIGH]

Software installed and run as a non-privileged user may conduct improper GPU system calls to cause mismanagement of resources reference counting creating a potential use after free scenario. [CVSS 8.8 HIGH]

A hardware vulnerability allows exfiltration of intermediate register values from secure workloads running in ARM TrustZone or similar TEE environments. Non-secure applications can read secure-world register contents.

Software installed and run as a non-privileged user may conduct improper GPU system calls to trigger reads of stale data that can lead to kernel exceptions and write use-after-free. The Use After Free common weakness enumeration was chosen as the stale data can include handles to resources in which the reference counts can become unbalanced. This can lead to the premature destruction of a resource while in use.

Kernel or driver software installed on a Guest VM may post improper commands to the GPU Firmware to exploit a TOCTOU race condition and trigger a read and/or write of data outside the allotted memory. Rated high severity (CVSS 7.4), this vulnerability is remotely exploitable, no authentication required. No vendor patch available.

Software installed and run as a non-privileged user may conduct improper GPU system calls to gain write permissions to memory buffers exported as read-only. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.

Software installed and run as a non-privileged user may conduct improper GPU system calls to trigger NULL pointer dereference kernel exceptions. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity. No vendor patch available.

Possible memory leak or kernel exceptions caused by reading kernel heap data after free or NULL pointer dereference kernel exception. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.

CVE-2025-46708 is a security vulnerability (CVSS 4.3). Remediation should follow standard vulnerability management procedures.

Software installed and running inside a Guest VM may override Firmware's state and gain access to the GPU.

Possible kernel exceptions caused by reading and writing kernel heap data after free.

GPU privilege escalation vulnerability allowing non-privileged users to conduct improper GPU system calls that bypass GPU hardware protections and write to arbitrary physical memory pages, achieving complete system compromise. The vulnerability affects GPU driver implementations across multiple vendors and has a CVSS score of 7.8 (High) with local attack vector requiring low privileges but no user interaction. Without KEV confirmation, EPSS score, or confirmed public POC in the provided data, the real-world exploitation risk remains moderate but should be treated as significant due to the nature of GPU memory access primitives in modern systems.

Kernel software installed and running inside a Guest VM may exploit memory shared with the GPU Firmware to write data outside the Guest's virtualised GPU memory. Rated high severity (CVSS 8.2), this vulnerability is no authentication required, low attack complexity. No vendor patch available.
