   An update that fixes 14 vulnerabilities is now available.

Description:



   The SUSE Linux Enterprise 12 SP1 kernel was updated to receive various
   security and bugfixes.

   The following security bugs were fixed:

   - CVE-2017-16939: The XFRM dump policy implementation in
     net/xfrm/xfrm_user.c in the Linux kernel allowed local users to gain
     privileges or cause a denial of service (use-after-free) via a crafted
     SO_RCVBUF setsockopt system call in conjunction with XFRM_MSG_GETPOLICY
     Netlink messages. (bnc#1069702)
   - CVE-2017-1000405: mm, thp: do not dirty huge pages on read fault
     (bnc#1069496).
   - CVE-2017-16649: The usbnet_generic_cdc_bind function in
     drivers/net/usb/cdc_ether.c in the Linux kernel allowed local users to
     cause a denial of service (divide-by-zero error and system crash) or
     possibly have unspecified other impact via a crafted USB device.
     (bnc#1067085)
   - CVE-2014-0038: The compat_sys_recvmmsg function in net/compat.c, when
     CONFIG_X86_X32 is enabled, allowed local users to gain privileges via a
     recvmmsg system call with a crafted timeout pointer parameter
     (bnc#860993).
   - CVE-2017-16650: The qmi_wwan_bind function in drivers/net/usb/qmi_wwan.c
     in the Linux kernel allowed local users to cause a denial of service
     (divide-by-zero error and system crash) or possibly have unspecified
     other impact via a crafted USB device. (bnc#1067086)
   - CVE-2017-16535: The usb_get_bos_descriptor function in
     drivers/usb/core/config.c in the Linux kernel allowed local users to
     cause a denial of service (out-of-bounds read and system crash) or
     possibly have unspecified other impact via a crafted USB device.
     (bnc#1066700)
   - CVE-2017-15102: The tower_probe function in
     drivers/usb/misc/legousbtower.c in the Linux kernel allowed local users     (who are physically proximate for inserting a crafted USB device) to
     gain privileges by leveraging a write-what-where condition that occurs     after a race condition and a NULL pointer dereference. (bnc#1066705)
   - CVE-2017-16531: drivers/usb/core/config.c in the Linux kernel allowed
     local users to cause a denial of service (out-of-bounds read and system
     crash) or possibly have unspecified other impact via a crafted USB
     device, related to the USB_DT_INTERFACE_ASSOCIATION descriptor.
     (bnc#1066671)
   - CVE-2017-12193: The assoc_array_insert_into_terminal_node function in
     lib/assoc_array.c in the Linux kernel mishandled node splitting, which
     allowed local users to cause a denial of service (NULL pointer
     dereference and panic) via a crafted application, as demonstrated by the
     keyring key type, and key addition and link creation operations.
     (bnc#1066192)
   - CVE-2017-16529: The snd_usb_create_streams function in sound/usb/card.c
     in the Linux kernel allowed local users to cause a denial of service
     (out-of-bounds read and system crash) or possibly have unspecified other
     impact via a crafted USB device. (bnc#1066650)
   - CVE-2017-16525: The usb_serial_console_disconnect function in
     drivers/usb/serial/console.c in the Linux kernel allowed local users to
     cause a denial of service (use-after-free and system crash) or possibly
     have unspecified other impact via a crafted USB device, related to
     disconnection and failed setup. (bnc#1066618)
   - CVE-2017-16537: The imon_probe function in drivers/media/rc/imon.c in
     the Linux kernel allowed local users to cause a denial of service (NULL
     pointer dereference and system crash) or possibly have unspecified other
     impact via a crafted USB device. (bnc#1066573)
   - CVE-2017-16536: The cx231xx_usb_probe function in
     drivers/media/usb/cx231xx/cx231xx-cards.c in the Linux kernel allowed
     local users to cause a denial of service (NULL pointer dereference and
     system crash) or possibly have unspecified other impact via a crafted
     USB device. (bnc#1066606)
   - CVE-2017-16527: sound/usb/mixer.c in the Linux kernel allowed local
     users to cause a denial of service (snd_usb_mixer_interrupt
     use-after-free and system crash) or possibly have unspecified other
     impact via a crafted USB device. (bnc#1066625)
