CVE-2016-3961 (retired)

Priority
Description
Xen and the Linux kernel through 4.5.x do not properly suppress hugetlbfs
support in x86 PV guests, which allows local PV guest OS users to cause a
denial of service (guest OS crash) by attempting to access a hugetlbfs
mapped area.
Ubuntu-Description
Vitaly Kuznetsov discovered that the Linux kernel did not properly suppress
hugetlbfs support in X86 paravirtualized guests. An attacker in the guest
OS could cause a denial of service (guest system crash).
