CVE-2026-45201 GPU DDK - Incorrect page size validation in PhysmemNewRamBackedPMR could lead to OOB read and/or write of arbitrary physical memory

Software installed and run as a non-privileged user may conduct improper GPU system calls to pass invalid log2 page size when allocating physical pages leading to OOB read and/or write due to improper validation of the said value. Such crafted log2 page size could lead to 4K pages being treated a...

CVE-2026-45201

This vulnerability affects the Imagination Technologies GPU DDK , specifically the PhysmemNewRamBackedPMR function. A non-privileged user can issue improper GPU system calls with an invalid log2 page size during physical page allocation, bypassing validation and causing out-of-bounds read and/or ...

CVE-2021-0945

In PMRCreate of the PowerVR kernel driver, a missing bounds check means it is possible to overwrite heap memory via PhysmemNewRamBackedPMR. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation...
