CVE-2024-12698Network attack vector

Authenticated service interruption via HTTP/2 rapid resets

Published Dec 18, 2024 · Updated Nov 20, 2025

Resource exhaustion in catalogd before 1.1.0, including OpenShift 4.18, allows remote authenticated users to interrupt service via rapid resets. The HTTP/2 server continues processing streams opened by authenticated clients after rapid resets, so repeated create-and-cancel cycles consume server resources. An authenticated network path to the catalogd endpoint is required; exploitation can exhaust availability without reported data disclosure or modification.
