CVE-2026-45198: CWE-822: Untrusted Pointer Dereference CWE-501: Trust Boundary Violation in Imagination Technologies Graphics DDK
CVE-2026-45198 is a vulnerability in Imagination Technologies Graphics DDK where the GPU firmware may use a pointer from non-secure memory controlled by the Rich Execution Environment (REE). This can lead to corruption of internal GPU firmware data if an attacker controls the REE kernel and modifies the pointer value. The issue arises from untrusted pointer dereference and trust boundary violation between secure and non-secure memory regions.
AI Analysis
Technical Summary
This vulnerability involves the GPU firmware booting with data from non-secure memory on platforms supporting a Trusted Execution Environment. The GPU firmware uses a pointer from the REE kernel memory when saving or retrieving internal data between private GPU memory and main memory. An attacker with control over the REE kernel can modify this pointer, potentially corrupting GPU firmware data. The flaw is categorized under CWE-822 (Untrusted Pointer Dereference) and CWE-501 (Trust Boundary Violation). No CVSS score or patch information is currently available.
Potential Impact
An attacker who has control over the REE kernel can manipulate pointers used by the GPU firmware, leading to corruption of internal GPU firmware data. This could affect the integrity of GPU operations, potentially causing unpredictable behavior or denial of service. There is no information about exploitation in the wild or further impact details.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or mitigation guidance is currently provided by the vendor. Users should monitor Imagination Technologies advisories for updates.
