Detailsinfo

A vulnerability has been found in Imagination Graphics DDK up to 1.18 RTM/23.2 RTM/24.2 RTM/25.3 RTM and classified as problematic. Affected by this vulnerability is an unknown code block. The manipulation with an unknown input leads to a use of out-of-range pointer offset vulnerability. The CWE definition for the vulnerability is CWE-823. The product performs pointer arithmetic on a valid pointer, but it uses an offset that can point outside of the intended range of valid memory locations for the resulting pointer. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

A web page that contains unusual GPU shader code is loaded into the GPU compiler process and can trigger a write out-of-bounds write crash in the GPU shader compiler library. On certain platforms, when the compiler process has system privileges this could enable further exploits on the device. An edge case using a very small value in GPU shader code can cause a segmentation fault in the GPU shader compiler due to am out-of-bounds write.

The advisory is shared at imaginationtech.com. This vulnerability is known as CVE-2026-21734 since 01/05/2026. Neither technical details nor an exploit are publicly available.
