"Improper invalidation for page table updates by a virtual guest
operating system for multiple Intel(R) Processors may allow an
authenticated user to potentially enable denial of service of the host
system via local access. (CVE-2018-12207)

Impact

A privileged guest user may use this flaw to induce a hardware Machine
Check Error (MCE) that halts the host processor and resultsin a
denial-of-service (DoS) scenario.

This is a hardware issue and requires kernel updates to remediate.
This issue impacts all BIG-IP platforms using the following Intel
processor families :

Xeon

Pentium Gold

Core X-series

Core i

Celeron G

The following BIG-IP platforms are vulnerable :

BIG-IP 2000s, 2200s, 4000s, 4200v, 5000s, 5050s, 5200v,5250v, 5250v
