CVE-2026-45199— GPU DDK - rgxfw_to_ptr() does not reject FW private data pointers
Quick assessment
Affected
Imagination Technologies Graphics DDK
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
安装在客户机虚拟机（Guest VM）内部并正在运行的内核软件，可能向 GPU 固件发送不正确的命令，从而触发对客户机虚拟化 GPU 内存范围之外的数据进行写入。 在客户机虚拟机内部安装并运行的软件可以向 GPU 发送命令，导致越界内存访问。攻击者可以利用此类越界访问实现权限提升。

Vulnerability Title
GPU DDK - rgxfw_to_ptr() does not reject FW private data pointers
Source: CVE Program / CVE List V5
Vulnerability Description
Kernel software installed and running inside a Guest VM may post improper commands to the GPU Firmware to trigger a write of data outside the Guest's virtualised GPU memory.
Software installed and run under a Guest VM can send commands to the GPU which result in out of bounds memory accesses. These can be used to escalate privileges.
