How to fix?

Upgrade SLES:15.5 emacs-el to version 27.2-150400.3.20.2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream emacs-el package and not the emacs-el package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

In elisp-mode.el in GNU Emacs through 30.0.92, a user who chooses to invoke elisp-completion-at-point (for code completion) on untrusted Emacs Lisp source code can trigger unsafe Lisp macro expansion that allows attackers to execute arbitrary code. (This unsafe expansion also occurs if a user chooses to enable on-the-fly diagnosis that byte compiles untrusted Emacs Lisp source code.)
