Description Vladimir Vasilev 2026-10-20 08:10:57 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 the SVG parser and renderer of the Qt SVG module (QtSvg) in Qt Group Qt allows attackers to cause a denial of service (application crash via stack exhaustion) via a crafted SVG file with deeply nested elements.
