NVD Description

Note: Versions mentioned in the description apply only to the upstream qt6-qtbase-common package and not the qt6-qtbase-common package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

An attacker able to supply a crafted XML document to an application using QXmlStreamReader can cause disproportionate CPU consumption during parsing, making the application unresponsive (denial of service). Exploitation requires only that the application parse attacker-influenced XML; no authentication, privileges, or user interaction beyond ingesting the input are needed. There is no loss of confidentiality or integrity — no data disclosure, data modification, or code execution — and the impact is contained to the affected process.
