Detailsinfo

A vulnerability classified as very critical was found in Imagination Graphics DDK up to 1.18 RTM2/23.2 RTM2/24.2 RTM2/25.3 RTM/26.1 RTM2. Affected by this vulnerability is some unknown processing of the component KM driver. The manipulation with an unknown input leads to a integer overflow vulnerability. The CWE definition for the vulnerability is 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 can introduce other weaknesses when the calculation is used for resource management or execution control. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Software installed and run as a non-privileged user may conduct improper system calls to allocate physical memory. A 32-bit integer overflow in the KM driver during page-to-byte conversion of an allocation size can result in an undersized kernel buffer allocation. This may allow unallocated or previously allocated physical pages to be mapped into an attacker-controlled GPU MMU context, leading to disclosure of sensitive kernel data.

The advisory is shared at imaginationtech.com. This vulnerability is known as CVE-2026-19199 since 08/07/2026. The exploitation appears to be easy. An attack has to be approached locally. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 10/30/2026).

Upgrading to version 26.2 RTM eliminates this vulnerability.
