Package : linux-lts
Type : privilege escalation
Remote : No
Link : https://security.archlinux.org/AVG-150
The package linux-lts before version 4.4.44-1 is vulnerable to

The problem has been fixed upstream in version 4.4.44.
The Linux kernel > 3.6-rc1, when built with Kernel-based Virtual
Machine (CONFIG_KVM) support, is vulnerable to an incorrect segment
selector (SS) value error. It could occur loading values into SS
register in long mode.
A user/process inside a guest host could use this flaw to crash the
guest, resulting in denial of service, or potentially escalate their
privileges inside the guest system on an AMD processor.
A local attacker in a guest host is able to crash the system or
escalate privileges inside the guest on an AMD processor.
