Updated kernel packages fixes security vulnerabilities

This update is based on upstream 4.4.36 and fixes at least the following security issues: The TCP stack in the Linux kernel before 4.8.10 mishandles skb truncation, which allows local users to cause a denial of service (system crash) via a crafted application that makes sendto system calls, related to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c (CVE-2016-8645). The mpi_powm function in lib/mpi/mpi-pow.c in the Linux kernel through 4.8.11 does not ensure that memory is allocated for limb data, which allows local users to cause a denial of service (stack memory corruption and panic) via an add_key system call for an RSA key with a zero exponent (CVE-2016-8650). A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets implementation in the Linux kernel networking subsystem handled synchronization while creating the TPACKET_V3 ring buffer. A local user able to open a raw packet socket (requires the CAP_NET_RAW capability) could use this flaw to elevate their privileges on the system (CVE-2016-8655). Linux kernel built with the Kernel-based Virtual Machine(CONFIG_KVM) support is vulnerable to an information leakage issue. It could occur on x86 platform, while emulating instructions in 32bit mode. A user/process could use this flaw to leak host kernel memory bytes (CVE-2016-9756). A bug in SO_{SND|RCV}BUFFORCE setsockopt() implementation allows CAP_NET_ADMIN users to set negative sk_sndbuf or sk_rcvbuf values. A user could use this flaw to cause various memory corruptions, crashes and OOM (CVE-2016-9793). For other fixes in this update, see the referenced changelogs.
