CVE-2026-45195
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedKernel software installed and running inside a Host VM may post improper commands to the GPU Firmware to trigger a memory read or write outside the permitted range of memory for the host kernel. Addresses passed to the GPU Firmware can be used by the Firmware for more privileged memory accesses than are permitted by the system.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceKernel software running inside a Host VM can send improper commands to the GPU Firmware, allowing memory reads or writes outside the permitted range for the host kernel. The addresses passed to GPU Firmware enable more privileged memory accesses than the system permits, creating a boundary violation in the virtualization layer.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Imagination Technologies GPU driver presenceCheck system for Imagination Technologies GPU driver modules or software (commonly found in /sys/module/, lsmod output, or driver package listings)Affected if No Imagination Technologies GPU driver is found, this CVE does not apply
-
Determine installed DDK/driver versionQuery the installed Imagination Technologies driver version through system utilities (modinfo, driver package manager, or /proc/driver/ entries) and compare against affected versions: <= 25.3 or = 26.1Affected if Installed version is 25.3 or lower, or exactly 26.1
-
Verify virtualization environment with GPU accessDetermine if the system is running as a VM (hypervisor detection) with GPU passthrough, vGPU, or virtualization features enabled that allow guest VM kernel software to communicate with GPU firmwareAffected if Running as a VM with direct or virtualized GPU access to firmware interfaces
-
Check GPU firmware communication interfaceInspect system configuration files, hypervisor settings, or driver parameters that control VM-to-GPU-firmware command paths (look for settings related to firmware access, GPU virtualization, or privileged memory mapping)Affected if Configuration allows guest VM kernel software to send commands directly to GPU firmware without hypervisor mediation
System is affected only if Imagination Technologies GPU driver version is 25.3 or lower or exactly 26.1, AND the environment uses virtualization where guest VMs can send commands directly to GPU firmware.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor-provided GPU firmware updates and ensure hypervisor is patched to restrict GPU firmware memory access privileges. Consider VM memory access controls until patches are applied.
