Looking at upstream, Red Hat never released kernel-4.18.0-193.14.2.el8_2 
into the wild.  The RHEL update 
(https://access.redhat.com/errata/RHSA-2020:3218) was 
kernel-4.18.0-193.14.3.el8_2, which is why that's the version in git 
(pushed from Red Hat's internal RelEng systems).  -193.14.2.el8_2 
appears to be something unique to CentOS.  Looking at the changelog of 
the CentOS package vs the RHEL one, this changelog entry is missing:

* Mon Jul 20 2020 Bruno Meneguele <bmeneg at redhat.com> 
- Reverse keys order for dual-signing (Frantisek Hrbata) [1837433 
1837434] {CVE-2020-10713}

Something to do with differences between the way RHEL and CentOS do 
Secure Boot signing, perhaps?
