Summary
The vmwgfx driver in the Linux kernel did not validate the pitch from userspace together with the box dimensions before copying data from the underlying surface. A local user with low privileges can trigger possible out of bounds reads through cursor snooping. CVSS 3.1 scores it 7.8 (HIGH), with high impact to confidentiality, integrity and availability. Red Hat rates it Moderate, and CISA does not list it in KEV.
