Detailsinfo

A vulnerability classified as very critical has been found in Imagination Graphics DDK up to 1.18 RTM2/23.2 RTM2/24.2 RTM2/25.3 RTM/26.1 RTM0. This affects an unknown functionality of the component GPU Firmware. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Kernel software installed and running inside a Guest VM may post improper commands to the GPU Firmware to trigger a write of data outside the Guest's virtualised GPU memory. Out of bounds accesses triggered by malware introduced to a Guest KMD could allow privilege escalation which escapes virtualization boundaries.
