"Alexandre Oliva reported a race condition flaw in the btrfs file
system's handling of extended attributes (xattrs). A local attacker
could exploit this flaw to bypass ACLs and potentially escalate
privileges. (CVE-2014-9710)

A memory corruption issue was discovered in AES decryption when using
the Intel AES-NI accelerated code path. A remote attacker could
exploit this flaw to cause a denial of service (system crash) or
potentially escalate privileges on Intel base machines with AEC-GCM
mode IPSec security association. (CVE-2015-3331)

A flaw was discovered in the Linux kernel's IPv4 networking when using
TCP fast open to initiate a connection. An unprivileged local user
could exploit this flaw to cause a denial of service (system crash).
(CVE-2015-3332).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
