How to fix?

Upgrade SLES:15.7 xen-tools to version 4.20.2_04-150700.3.22.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream xen-tools package and not the xen-tools package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

Shadow mode tracing code uses a set of per-CPU variables to avoid cumbersome parameter passing. Some of these variables are written to with guest controlled data, of guest controllable size. That size can be larger than the variable, and bounding of the writes was missing.
