Summary

Imagination Graphics DDK versions 1.18 RTM2, 23.2 RTM2, 24.2 RTM2, 25.1 RTM2 through 25.3 RTM, and 26.1 RTM2 are affected. An integer truncation (CWE-823) occurs when mapping GPU buffer pages in the 0GB to 4GB range, which causes mapping errors and limits the functionality of the kernel mode driver. A remote attacker with no privileges and no user interaction can exploit this flaw, with high impact to confidentiality, integrity and availability.

Description from the CNA

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.
