Impact

Hardware cryptographic acceleration fails and TMM may stop responding,
which causes a failover event if the BIG-IP system is configured as
part of a device group.This vulnerability applies to the following
platforms :

i4000, i4600, i4800, YK i4000

i5000, i5600, i5800, HRC-i5000, HRC-i5800, i5820-DF

i7000, i7600, i7800, i7000-D, i7820-DF

i10000, i10600, i10800, i10000-D, HRC-i10800

i11000, i11600, i11800, i11000-DS, i11000-D

i15000, i15600, i15800, i15000-N

BIG-IP Virtual Edition (VE)

Note : BIG-IP VE cryptographic and compression offload is a licensed
feature available only on the KVM hypervisor. If you have licensed
this feature(a BIG-IP VE using the affected Intel QAT hardware
[Lewisburg and Lewis Hill QAT devices]with an affected Intel QAT
SR-IOV VF driver included in the BIG-IP VE version)then the Intel QAT
PF (Lewisburg and Lewis Hill QAT devices) driver installed on the host
is vulnerable. Under this very explicit KVM scenario, a BIG-IP VE is
vulnerable."
