DESCRIPTION

* CVE-2016-3157: Xen I/O port access privilege escalation in x86-64.

User mode processes not supposed to be able to access I/O ports may
be granted such permission, potentially resulting in one or more of
in-guest privilege escalation, guest crashes (Denial of Service), or
in-guest information leaks.


* BUG in HugeTLB filesystem file truncation and fallocate hole punch.

Improper handling of offset in the HugeTLB filesystem can cause a BUG
during file truncation or using the fallocate hole punch operation.
