Description Vladimir Vasilev 2026-09-23 07:42:12 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

GNU Emacs 28.1 through 31.1 allows arbitrary code execution upon opening a file, because an untrusted value of read-symbol-shorthands affects the intern and unintern functions. This affects the default configuration; no particular user settings are required to trigger it.
Comment 1 Peter Oliver 2026-09-24 12:02:49 UTC 
It is my understanding that this is already fixed on all current Fedora branches (e.g., https://src.fedoraproject.org/rpms/emacs/c/34f2c1438b33a8034ff7b677788dec2e31dcf8af?branch=rawhide).  Please reopen if you believe that this is not the case.
