Vulnerability from github – Published: 2026-06-26 18:33 – Updated: 2026-06-26 21:32

Details

Kernel software installed and running inside a Host VM may post improper commands to the GPU Firmware to trigger a memory read or write outside the permitted range of memory for the host kernel.

Addresses passed to the GPU Firmware can be used by the Firmware for more privileged memory accesses than are permitted by the system.

Severity ?

7.8 (High)


                  
                    CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
