  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-2020-25212: Fixed nfs getxattr kernel panic and memory overflow that
  could lead to crashes or privilege escalations (bsc#1176381).

  - CVE-2020-14381: Fixed inode life-time issue in futex handling
  (bsc#1176011).

  - CVE-2020-25643: Memory corruption and a read overflow is caused by
  improper input validation in the ppp_cp_parse_cr function which can
  cause the system to crash or cause a denial of service. The highest
  threat from this vulnerability is to data confidentiality and integrity
  as well as system availability (bnc#1177206).

  - CVE-2020-25641: A zero-length biovec request issued by the block
  subsystem could cause the kernel to enter an infinite loop, causing a
  denial of service. This flaw allowed a local attacker with basic
  privileges to issue requests to a block device, resulting in a denial of
  service. The highest threat from this vulnerability is to system
  availability (bnc#1177121).

  - CVE-2020-26088: A missing CAP_NET_RAW check in NFC socket creation in
  net/nfc/rawsock.c could be used by local attackers to create raw
  sockets, bypassing security mechanisms, aka CID-26896f01467a
  (bnc#1176990).

  - CVE-2020-14390: When changing screen size, an out-of-bounds memory write
  can occur leading to memory corruption or a denial of service. Due to
  the nature of the flaw, privilege escalation cannot be fully ruled out
  (bnc#1176235 bnc#1176278).

  - CVE-2020-0432: In skb_to_mamac of networking.c, there is a possible out
  of bounds write due to an integer overflow. This could lead to local
  escalation of privilege with no additional execution privileges needed.
  User interaction is not needed for exploitation (bnc#1176721).

  - CVE-2020-0427: In create_pinctrl of core.c, there is a possible out of
  bounds read due to a use after free. This could lead to local
  information disclosure with no additional execution privileges needed.
  User interaction is not needed for exploitation (bnc#1176725).

  - CVE-2020-0431: In kbd_keycode of keyboard.c, there is a possible out of
  bounds write due to a missing bounds check. This could lead to local
  escalation of privilege with no additional execution privileges needed.
  User interaction is not needed for exploitation (bnc#1176722).

  - CVE-2020-0404: In uvc_scan_chain_forward of uvc_driver.c, there is a
  possible linked list corruption due to an unusual root cause. This could
  lead to local escalation of privilege in the kernel with no additional
  execution privileges
