CVE-2022-35236 Details
Description
In BIG-IP Versions 16.1.x before 16.1.2.2, 15.1.x before 15.1.6.1, and 14.1.x before 14.1.5, when an HTTP2 profile is configured on a virtual server, undisclosed traffic can cause an increase in memory resource utilization. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
A vulnerability exists in F5 BIG-IP versions 16.1.x prior to 16.1.2.2, 15.1.x prior to 15.1.6.1, and 14.1.x prior to 14.1.5. When an HTTP2 profile is active on a virtual server, certain undisclosed traffic can unintentionally increase memory usage. This rise in memory consumption can degrade system performance, potentially causing the Traffic Management Microkernel (TMM) process to crash or require a manual restart. This issue represents a data plane problem, with no exposure to the control plane.
Users can upgrade to BIG-IP versions 16.1.2.2, 15.1.6.1, or 14.1.5 to address this vulnerability. F5 also recommends configuring BIG-IP systems with high availability to mitigate the impact.
