  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.120 to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2017-13166: An elevation of privilege vulnerability in the v4l2
 video driver. (bnc#1072865).
- CVE-2017-15951: The KEYS subsystem did not correctly synchronize the
 actions of updating versus finding a key in the 'negative' state to
 avoid a race condition, which allowed local users to cause a denial of
 service or possibly have unspecified other impact via crafted system
 calls (bnc#1062840 bnc#1065615).
- CVE-2017-16644: The hdpvr_probe function in
 drivers/media/usb/hdpvr/hdpvr-core.c allowed local users to cause a
 denial of service (improper error handling and system crash) or possibly
 have unspecified other impact via a crafted USB device (bnc#1067118).
- CVE-2017-16912: The 'get_pipe()' function (drivers/usb/usbip/stub_rx.c)
 allowed attackers to cause a denial of service (out-of-bounds read) via
 a specially crafted USB over IP packet (bnc#1078673).
- CVE-2017-16913: The 'stub_recv_cmd_submit()' function
 (drivers/usb/usbip/stub_rx.c) when handling CMD_SUBMIT packets allowed
 attackers to cause a denial of service (arbitrary memory allocation) via
 a specially crafted USB over IP packet (bnc#1078672).
- CVE-2017-17975: Use-after-free in the usbtv_probe function in
 drivers/media/usb/usbtv/usbtv-core.c allowed attackers to cause a denial
 of service (system crash) or possibly have unspecified other impact by
 triggering failure of audio registration, because a kfree of the usbtv
 data structure occurs during a usbtv_video_free call, but the
 usbtv_video_fail label's code attempts to both access and free this data
 structure (bnc#1074426).
- CVE-2017-18174: The amd_gpio_remove function in
 drivers/pinctrl/pinctrl-amd.c calls the pinctrl_unregister function,
 leading to a double free (bnc#1080533).
- CVE-2017-18208: The madvise_willneed function in mm/madvise.c allowed
 local users to cause a denial of service (infinite loop) by triggering
 use of MADVISE_WILLNEED for a DAX mapping (bnc#1083494).
- CVE-2018-1000026: A insufficient input validation vulnerability in bnx2x
 network card driver could result in DoS: Network card firmware assertion
 takes card off-line. This attack appear to be exploitable via An
 attacker on a must pass a very large, specially crafted packet to the
 bnx2x card. This can be done from an untrusted guest VM. (bnc#1079384).
- CVE-2018-8087: Memory leak in the hwsim_new_radio_nl function in
 drivers/net/wireless/mac80211_hwsim.c allowed local users to cause a
 denial of service (memory consumption) by triggering an out-of-array
 error case (bnc#1085053).
- CVE-2018-1068: Insufficient user provided offset checking in the
 ebtables compat code allowed local attackers to overwrite kernel memory
 and potentially execute code. (bsc#1085107)
The following non-security bugs were fixed:
