  script_tag(name:"insight", value:"The openSUSE Leap 15.2 kernel was updated to receive various security and
  bugfixes.

  The following security bugs were fixed:

  - CVE-2019-19462: relay_open in kernel/relay.c allowed local users to
  cause a denial of service (such as relay blockage) by triggering a NULL
  alloc_percpu result (bnc#1158265).

  - CVE-2019-20810: go7007_snd_init in drivers/media/usb/go7007/snd-go7007.c
  did not call snd_card_free for a failure path, which causes a memory
  leak, aka CID-9453264ef586 (bnc#1172458).

  - CVE-2019-20812: The prb_calc_retire_blk_tmo() function in
  net/packet/af_packet.c can result in a denial of service (CPU
  consumption and soft lockup) in a certain failure case involving
  TPACKET_V3, aka CID-b43d1f9f7067 (bnc#1172453).

  - CVE-2020-10711: A NULL pointer dereference flaw was found in the Linux
  kernel's SELinux subsystem. This flaw occurs while importing the
  Commercial IP Security Option (CIPSO) protocol's category bitmap into
  the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine.
  While processing the CIPSO restricted bitmap tag in the
  'cipso_v4_parsetag_rbm' routine, it sets the security attribute to
  indicate that the category bitmap is present, even if it has not been
  allocated. This issue leads to a NULL pointer dereference issue while
  importing the same category bitmap into SELinux. This flaw allowed a
  remote network user to crash the system kernel, resulting in a denial of
  service (bnc#1171191).

  - CVE-2020-10732: A flaw was found in the implementation of Userspace core
  dumps. This flaw allowed an attacker with a local account to crash a
  trivial program and exfiltrate private kernel data (bnc#1171220).

  - CVE-2020-10751: SELinux LSM hook implementation before version 5.7,
  where it incorrectly assumed that an skb would only contain a single
  netlink message. The hook would incorrectly only validate the first
  netlink message in the skb and allow or deny the rest of the messages
  within the skb with the granted permission without further processing
  (bnc#1171189).

  - CVE-2020-10766: Fixed rogue cross-process SSBD shutdown. Linux scheduler
  logical bug allowed an attacker to turn off the SSBD protection.
  (bnc#1172781).

  - CVE-2020-10767: Fixed that Indirect Branch Prediction Barrier is
  force-disabled when STIBP is unavailable or enhanced IBRS is available.
  (bnc#1172782).

  - CVE-2020-10768: Fixed that indirect branch speculation can be enabled
  after it was force-disabled by the PR_SPEC_FORCE_DISABLE prctl command
  (bnc#1172783).

  - CVE-2020-10773: Fixed a kernel stack information leak on s390/s390x.
  (bnc#11729 ...
