CVE-2026-45202

A flaw in Imagination GPU DDK's _FreeOSPages_Fast function fails to track state of upgraded higher-order CMA allocations, enabling a non-privileged user to trigger memory leaks or double frees via GPU syscalls, potentially causing kernel heap corruption. No exploit code or in-the-wild exploitatio...

CVE-2026-45201

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-2026-45199

The rgxfw_to_ptr() function in Imagination's GPU DDK fails to validate firmware private data pointers, allowing Guest VM kernel software to trigger out-of-bounds memory writes via GPU firmware commands, enabling privilege escalation. Exploitation status is not provided. Reference: https://www.ima...

CVE-2026-22163 GPU DDK - Unsafe writing of MMU PT entries on systems with 32-bit host CPU

Requires malware code to misuse the DDK kernel module IOCTL interface. Such code can use the interface in an unsupported way that allows subversion of the GPU to perform writes to arbitrary physical memory pages. The product utilises a shared resource in a concurrent manner but does not attempt t...

CVE-2026-21736

CVE-2026-21736 is a GPU DDK vulnerability where a non-privileged user can perform improper GPU system calls to gain write access to read-only wrapped user-mode memory.
