CVE-2016-3961 xsa174 xen: hugetlbfs use may crash PV Linux guests (XSA-174)
ISSUE DESCRIPTION
Huge (2Mb) pages are generally unavailable to PV guests. Since x86
Linux pvops-based kernels are generally multi purpose, they would
normally be built with hugetlbfs support enabled. Use of that
functionality by an application in a PV guest would cause an
infinite page fault loop, and an OOPS to occur upon an attempt to
terminate the hung application.
IMPACT
Depending on the guest kernel configuration, the OOPS could result
in a kernel crash (guest DoS).
VULNERABLE SYSTEMS
All upstream x86 Linux versions operating as PV Xen guests are
vulnerable.
ARM systems are not vulnerable. x86 HVM guests are not vulnerable.
x86 Linux versions derived from linux-2.6.18-xen.hg (XenoLinux) are not
