  script_tag(name:"insight", value:"This kernel-linus update is based on upstream 4.4.92 and fixes at least the
following security issues:

A security flaw was discovered in nl80211_set_rekey_data() function in the
Linux kernel since v3.1-rc1 through v4.13. This function does not check
whether the required attributes are present in a netlink request. This
request can be issued by a user with CAP_NET_ADMIN privilege and may result
in NULL dereference and a system crash (CVE-2017-12153).

Linux kernel built with the KVM visualization support (CONFIG_KVM), with
nested visualization (nVMX) feature enabled (nested=1), is vulnerable to a
crash due to disabled external interrupts. As L2 guest could acce s (r/w)
hardware CR8 register of the host(L0). In a nested visualization setup,
L2 guest user could use this flaw to potentially crash the host(L0)
resulting in DoS (CVE-2017-12154).

The tcp_disconnect function in net/ipv4/tcp.c in the Linux kernel before
4.12 allows local users to cause a denial of service (__tcp_select_window
divide-by-zero error and system crash) by triggering a disconnect within a
certain tcp_recvmsg code path (CVE-2017-14106).

The atyfb_ioctl function in drivers/video/fbdev/aty/atyfb_base.c in the
Linux kernel through 4.12.10 does not initialize a certain data structure,
which allows local users to obtain sensitive information from kernel stack
memory by reading locations associated with padding bytes (CVE-2017-14156).

It was found that the iscsi_if_rx() function in scsi_transport_iscsi.c in
the Linux kernel since v2.6.24-rc1 through 4.13.2 allows local users to
cause a denial of service (a system panic) by making a number of certain
syscalls by leveraging incorrect length validation in the kernel code
(CVE-2017-14489).

The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel before 4.13.4
allows local users to obtain sensitive information from uninitialized kernel
heap-memory locations via an SG_GET_REQUEST_TABLE ioctl call for /dev/sg0
(CVE-2017-14991).

A reachable assertion failure flaw was found in the Linux kernel built with
KVM virtualisation(CONFIG_KVM) support with Virtual Function I/O feature
(CONFIG_VFIO) enabled. This failure could occur if a malicious guest device
sent a virtual interrupt (guest IRQ) with a larger (>1024) index value
(CVE-2017-1000252).
