K79933541 : HTTP2 profile vulnerability CVE-2022-35236

Security Advisory Description

When an HTTP2 profile is configured on a virtual server, undisclosed traffic can cause an increase in memory resource utilization. (CVE-2022-35236)

Impact

System performance can degrade until the TMM process is either forced to restart or is manually restarted. This vulnerability allows a remote, unauthenticated attacker to cause a degradation of service that can lead to a denial-of-service (DoS) on the BIG-IP system. There is no control plane exposure; this is a data plane issue only.
