Summary
On GPU systems with the fix for CVE-2026-49746 applied, the graphics buffer mapping range is limited, causing errors when mapping outside that range. Integer truncation when mapping GPU buffer pages in the 0GB-4GB range produces errors and limits kernel mode driver functionality.
Risk Assessment
Errors and reduced kernel driver functionality occur when mapping buffers in the 0-4 GB range. This may cause graphics instability or application crashes.
Recommendation
Update the GPU driver to a version containing the fix for this issue. Verify graphics application behavior after updating.

Original NVD description (English source)
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.
