There is no fixed version for RHEL:8 emacs.
NVD Description
Note: Versions mentioned in the description apply only to the upstream emacs package and not the emacs package as distributed by RHEL.
See How to fix? for RHEL:8 relevant fixed versions and status.
An issue was discovered in GNU Emacs through 28.2. In ruby-mode.el, the ruby-find-library-file function has a local command injection vulnerability. The ruby-find-library-file function is an interactive function, and bound to C-c C-f. Inside the function, the external command gem is called through shell-command-to-string, but the feature-name parameters are not escaped. Thus, malicious Ruby source files may cause commands to be executed.
