How to fix?

Upgrade Ubuntu:18.04 qemu to version 1:2.11+dfsg-1ubuntu7.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu package and not the qemu package as distributed by Ubuntu. See How to fix? for Ubuntu:18.04 relevant fixed versions and status.

hw/input/ps2.c in Qemu does not validate 'rptr' and 'count' values during guest migration, leading to out-of-bounds access.
