Description Vladimir Vasilev 2026-09-16 11:01:12 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.

QDomDocument XML parsing is vulnerable to a remotely-triggerable denial-of-service crash when processing untrusted input.
Comment 1 Vladimir Vasilev 2026-09-16 11:05:19 UTC 
Our manifests shows that this is fixed in F44 (mingw-qt6-qtbase-6.11.2-1.fc44) but not in F43.
