Name of the Vulnerable Software and Affected Versions versions prior to 2026-21736

Description Software running with non-privileged user access may be able to make incorrect system calls to the GPU, potentially gaining write access to memory that should be read-only. This is due to improper handling of memory protections for user-mode wrapped memory resources. The issue involves an insufficient permission check within the PhysmemWrapExtMem() function when write attribute support is enabled.
