There is no fixed version for RHEL:8 qemu-kvm-core.
NVD Description
Note: Versions mentioned in the description apply only to the upstream qemu-kvm-core package and not the qemu-kvm-core package as distributed by RHEL.
See How to fix? for RHEL:8 relevant fixed versions and status.
In libslirp 4.1.0, as used in QEMU 4.2.0, tcp_subr.c misuses snprintf return values, leading to a buffer overflow in later code.
