NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-chardev-spice package and not the qemu-chardev-spice package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

slirp.c in libslirp through 4.3.1 has a buffer over-read because it tries to read a certain amount of header data even if that exceeds the total packet length.
