Description Vladimir Vasilev 2026-10-07 18:29:34 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.

Uncontrolled recursion in Qt's QDomDocument serialization (QtXml) lets deeply nested untrusted XML crash the app via stack exhaustion (DoS only).
