How to fix?

Upgrade RHEL:8 go-toolset:rhel8/golang-misc to version 0:1.15.14-1.module+el8.4.0+11833+614b07b8 or higher.
This issue was patched in RHSA-2021:3076.

NVD Description

Note: Versions mentioned in the description apply only to the upstream go-toolset:rhel8/golang-misc package and not the go-toolset:rhel8/golang-misc package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

The crypto/tls package of Go through 1.16.5 does not properly assert that the type of public key in an X.509 certificate matches the expected type when doing a RSA based key exchange, allowing a malicious TLS server to cause a TLS client to panic.
