Description:	Summary: The remote host is missing an update for the 'linux' package(s) announced via the USN-3168-1 advisory. Vulnerability Insight: Dmitry Vyukov discovered that the KVM implementation in the Linux kernel did not properly initialize the Code Segment (CS) in certain error cases. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2016-9756) Andrey Konovalov discovered that signed integer overflows existed in the setsockopt() system call when handling the SO_SNDBUFFORCE and SO_RCVBUFFORCE options. A local attacker with the CAP_NET_ADMIN capability could use this to cause a denial of service (system crash or memory corruption). (CVE-2016-9793) Baozeng Ding discovered a race condition that could lead to a use-after- free in the Advanced Linux Sound Architecture (ALSA) subsystem of the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-9794) Baozeng Ding discovered a double free in the netlink_dump() function in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-9806) Affected Software/OS: 'linux' package(s) on Ubuntu 14.04. Solution: Please install the updated package(s).
