USN-7547-1

It was discovered that Tornado inefficiently handled requests when parsing certain form data. An attacker could possibly use this issue to increase resource utilization leading to a denial of service. This issue was only addressed in Ubuntu 24.04 LTS and Ubuntu 22.04 LTS. (CVE-2025-47287)
