CVE-2026-21734

Name of the Vulnerable Software and Affected Versions The product name cannot be determined (affected versions not specified)

Description A GPU shader compiler library contains a flaw where loading a web page with unusual GPU shader code can trigger an out-of-bounds write. This occurs during an edge case involving a very small value in the shader code, leading to a segmentation fault—a specific type of crash that happens when a program attempts to access a memory location it is not allowed to access. On platforms where the compiler process operates with system privileges, this condition could facilitate further exploits on the device.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
