Symantec Endpoint Protection does not support RHEL6.7 now, however, there are quite a lot vulnerabilities in RHEL6.6.
Due to security issue, we have to upgrade RHEL patches to RHEL6.7.
I would like to suggestion SEP :
1. Support RHEL 6.7 in coming release
2. Support level should based on kernel version of RHEL. (for my case, i will upgrade patches to RHEL6.7 but keep kernel in RHEL6.6
