Improper Memory Protection in Non-Privileged User GPU System Calls by Imagination Technologies

CVE-2026-21736

What is CVE-2026-21736?

This vulnerability arises from the insufficient protection of user-mode wrapped memory resources in Imagination Technologies' GPU drivers. When software is executed by a non-privileged user, it may exploit these memory protections, enabling unauthorized write access to areas of memory that should be read-only. Such a flaw could potentially allow an attacker to manipulate system operations or leak sensitive information, highlighting the importance of robust memory management practices in driver security.
