  script_tag(name:"insight", value:"The openSUSE Leap 15.1 kernel was updated to receive various security and
  bugfixes.

  The following security bugs were fixed:

  - CVE-2018-7191: In the tun subsystem dev_get_valid_name xwas not called
  before register_netdevice. This allowed local users to cause a denial of
  service (NULL pointer dereference and panic) via an ioctl(TUNSETIFF)
  call with a dev name containing a / character. This is similar to
  CVE-2013-4343 (bnc#1135603).

  - CVE-2019-11085: Insufficient input validation in Kernel Mode Driver in
  Intel(R) i915 Graphics for Linux may have allowed an authenticated user
  to potentially enable escalation of privilege via local access
  (bnc#1135278).

  - CVE-2019-11486: The Siemens R3964 line discipline driver in
  drivers/tty/n_r3964.c in the Linux kernel had multiple race conditions
  (bnc#1133188). It was disabled by default.

  - CVE-2019-11811: There is a use-after-free upon attempted read access to
  /proc/ioports after the ipmi_si module is removed, related to
  drivers/char/ipmi/ipmi_si_intf.c, drivers/char/ipmi/ipmi_si_mem_io.c,
  and drivers/char/ipmi/ipmi_si_port_io.c (bnc#1134397).

  - CVE-2019-11815: An issue was discovered in rds_tcp_kill_sock in
  net/rds/tcp.c kernel. There is a race condition leading to a
  use-after-free, related to net namespace cleanup (bnc#1134537).

  - CVE-2019-11833: fs/ext4/extents.c did not zero out the unused memory
  region in the extent tree block, which might allow local users to obtain
  sensitive information by reading uninitialized data in the filesystem
  (bnc#1135281).

  - CVE-2019-11884: The do_hidp_sock_ioctl function in
  net/bluetooth/hidp/sock.c allowed a local user to obtain potentially
  sensitive information from kernel stack memory via a HIDPCONNADD
  command, because a name field may not end with a '\0' character
  (bnc#1134848).

  - CVE-2019-3882: A flaw was found in the vfio interface implementation
  that permits violation of the user's locked memory limit. If a device is
  bound to a vfio driver, such as vfio-pci, and the local attacker is
  administratively granted ownership of the device, it may cause a system
  memory exhaustion and thus a denial of service (DoS). (bnc#1131416
  bnc#1131427).

  - CVE-2019-5489: The mincore() implementation in mm/mincore.c allowed
  local attackers to observe page cache access patterns of other processes
  on the same system, potentially allowing sniffing of secret information.
  (Fixing this affects the output of the fincore program.) Limited remote
  exploitation may be possible, as demonstrated by latency differences in
  accessing public files from an Apache HTTP Server.
