With the fix for CVE-2026-49746 applied, GPU graphics buffers can only be mapped within a 0 to 4GB range, and mapping outside that range fails. The sources describe an integer truncation when mapping GPU buffer pages that limits the kernel mode driver's functionality, and do not describe an attacker gain.

Each row is the first time that source carried this signal. The analyst’s rows are its own findings.
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.
