How to fix?

Upgrade RHEL:8 kernel-headers to version 0:4.18.0-240.el8 or higher.
This issue was patched in RHSA-2020:4431.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-headers package and not the kernel-headers package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

In the Linux kernel before 5.5.8, get_raw_socket in drivers/vhost/net.c lacks validation of an sk_family field, which might allow attackers to trigger kernel stack corruption via crafted system calls.
