Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.

In BIG-IP PEM versions 16.0.0-16.0.0.1, 15.1.0-15.1.0.5, 14.1.0-14.1.2.7, 13.1.0-13.1.3.4, 12.1.0-12.1.5.2, and 11.6.1-11.6.5.2, when processing Capabilities-Exchange-Answer (CEA) packets with certain attributes from the Policy and Charging Rules Function (PCRF) server, the Traffic Management Microkernel (TMM) may generate a core file and restart.

On BIG-IP 12.1.0-12.1.5, the TMM process may produce a core file in some cases when Ram Cache incorrectly optimizes stored data resulting in memory errors.

The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.
