CVE-2022-23030 · MEDIUM Severity

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L

On version 16.1.x before 16.1.2, 15.1.x before 15.1.4.1, 14.1.x before 14.1.4.5, and all versions of 13.1.x, when the BIG-IP Virtual Edition (VE) uses the ixlv driver (which is used in SR-IOV mode and requires Intel X710/XL710/XXV710 family of network adapters on the Hypervisor) and TCP Segmentation Offload configuration is enabled, undisclosed requests may cause an increase in CPU resource utilization. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
