  script_tag(name:"insight", value:"Example: The openSUSE Leap 42.3 kernel was updated to 4.4.180 to receive
  various security and bugfixes.

  The following security bugs were fixed:

  - CVE-2019-11477: A sequence of SACKs may have been crafted by a remote
  attacker such that one can trigger an integer overflow, leading to a
  kernel panic. (bsc#1137586).

  - CVE-2019-11478: It was possible to send a crafted sequence of SACKs
  which would fragment the TCP retransmission queue. A remote attacker may
  have been able to further exploit the fragmented queue to cause an
  expensive linked-list walk for subsequent SACKs received for that same
  TCP connection. (bsc#1137586)

  - CVE-2019-11479: It was possible to send a crafted sequence of SACKs
  which would fragment the RACK send map. A remote attacker may be able to
  further exploit the fragmented send map to cause an expensive
  linked-list walk for subsequent SACKs received for that same TCP
  connection. This would have resulted in excess resource consumption due
  to low mss values. (bsc#1137586)

  - CVE-2019-12819: The function __mdiobus_register() in
  drivers/net/phy/mdio_bus.c calls put_device(), which will trigger a
  fixed_mdio_bus_init use-after-free. This will cause a denial of service
  (bnc#1138291).

  - CVE-2019-12818: The nfc_llcp_build_tlv function in
  net/nfc/llcp_commands.c may return NULL. If the caller did not check for
  this, it will trigger a NULL pointer dereference. This will cause denial
  of service. This affects nfc_llcp_build_gb in net/nfc/llcp_core.c
  (bnc#1138293).

  - CVE-2019-12456: An issue was discovered in the MPT3COMMAND case in
  _ctl_ioctl_main in drivers/scsi/mpt3sas/mpt3sas_ctl.c that allowed local
  users to cause a denial of service or possibly have unspecified other
  impact by changing the value of ioc_number between two kernel reads of
  that value, aka a 'double fetch' vulnerability (bnc#1136922).

  - CVE-2019-12380: phys_efi_set_virtual_address_map in
  arch/x86/platform/efi/efi.c and efi_call_phys_prolog in
  arch/x86/platform/efi/efi_64.c mishandle memory allocation failures
  (bnc#1136598).

  - CVE-2019-11487: The Linux kernel allowed page->_refcount reference count
  overflow, with resultant use-after-free issues, if about 140 GiB of RAM
  exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c,
  include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c,
  mm/gup.c, and mm/hugetlb.c. It can occur with FUSE requests
  (bnc#1133190).

  - CVE-2019-3846: A flaw that allowed an attacker to corrupt memory and
  possibly escalate privileges was found in the mwifiex kernel module
  while connecting to a mal ...
