AI-suggested

Red Hat has released updated qt6-qtbase packages (version 6.12.0-1.2.hum1) that address this vulnerability. Users should apply these updates to remediate the issue. Additionally, it is recommended to ensure client applications only connect to trusted HTTP endpoints and configure application network settings to restrict maximum allowed response headers and body buffer sizes where supported.

Description

A resource consumption vulnerability exists in the Qt Network module's HTTP response handling. A remote attacker or malicious server can send a specially crafted HTTP response that causes excessive resource use, potentially leading to denial of service (DoS). This issue affects Red Hat Hardened Images RPMs containing qt6-qtbase packages. The vulnerability is tracked as CVE-2026-116337 and is rated as low severity by Red Hat.
