Detailsinfo

A vulnerability, which was classified as very critical, has been found in Imagination Graphics DDK up to 26.2 RTM. This issue affects an unknown code of the component System Call Handler. The manipulation with an unknown input leads to a integer overflow vulnerability. Using CWE to declare the problem leads to CWE-190. The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Software installed and run as a non-privileged user may conduct GPU system calls to trigger an integer overflow and allow OOB writes to GPU buffers. The integer overflow caused when mapping a GPU buffer >4GB causes corruption of array length, and can lead to kernel panics or out of bounds access.

The advisory is shared at imaginationtech.com. The identification of this vulnerability is CVE-2026-49747 since 06/01/2026. The exploitation is known to be easy.
