Last modified

CVE-2026-45197 is a low-severity vulnerability rated 2.5/10 on the CVSS scale. Kernel software installed and running inside a Guest VM may post improper commands to the GPU Firmware to trigger a read and/or write data outside the Guest's virtualised GPU memory. The firmware uses data provided by the Guest VM to set up accesses to memory. It validated this before use, but a TOCTOU bug was present which allowed the earlier check results to be invalidated.. EPSS estimates a 0.11% chance of exploitation in the next 30 days.
