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)
