NVD Description

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

A flaw was found in Cockpit. An unauthenticated remote attacker can exploit this vulnerability by initiating and sustaining numerous simultaneous connections to the cockpit-tls service. This forces the service to create an unbounded number of detached threads, consuming system resources such as memory and file descriptors. The primary consequence is a denial of service (DoS), leading to degradation or complete unavailability of the Cockpit service for legitimate users.
