Summary
The GPU Driver Development Kit (DDK) and the kernel mode graphics driver on affected GPU systems are impacted. Graphics buffers larger than 4GB cannot be mapped correctly after the security fix is applied, causing mapping errors and limiting driver functionality.

Read the original description
On GPU systems with the security vulnerability fix for CVE-2026-49746 applied, the mapping range of graphics buffers is limited which causes errors when the mapping outside of that range. Integer truncation caused when mapping GPU buffer pages in the buffer’s range 0GB - 4GB, produces error and limits the functionality of the kernel mode driver.
