NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu package and not the qemu package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

Qemu has integer overflows because IOReadHandler and its associated functions use a signed integer data type for a size value.
