   An update that solves 11 vulnerabilities and has 12 fixes
   is now available.

Description:

   The SUSE Linux Enterprise 12 SP3 kernel was updated to receive various
   security and bugfixes.

   The following security bugs were fixed:

   - CVE-2020-10135: Legacy pairing and secure-connections pairing
     authentication in Bluetooth may have allowed an unauthenticated user to
     complete authentication without pairing credentials via adjacent access.
     An unauthenticated, adjacent attacker could impersonate a Bluetooth
     BR/EDR master or slave to pair with a previously paired remote device to
     successfully complete the authentication procedure without knowing the
     link key (bnc#1171988).
   - CVE-2020-10711: A NULL pointer dereference flaw was found in the 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. This flaw allowed
 a
     remote network user to crash the system kernel, resulting in a denial of
     service (bnc#1171191).
   - CVE-2020-10751: A flaw was found in the SELinux LSM hook implementation,
     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-2019-20812: An issue was discovered in 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-2020-10732: 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-2020-0305: In cdev_get of char_dev.c, there is a possible
     use-after-free due to a race condition. This could lead to local
     escalation of privilege with System execution privileges needed. User
     interaction is not needed for exploitation (bnc#1174462).
   - CVE-2020-12771: btree_gc_coalesce in drivers/md/bcache/btree.c had a
     deadlock if a coalescing operation fails (bnc#1171732).
   - CVE-2020-10773: A kernel stack information leak on s390/s390x was fixed
     (bnc#1172999).
   - CVE-2020-14416: A race condition in tty->disc_data handling in the slip
     and slcan line discipline could lead to a use-after-free, aka
     CID-0ace17d56824. This affects drivers/net/slip/slip.c and
     drivers/net/can/slcan.c (bnc#1162002).
   - CVE-2020-13974: drivers/tty/vt/keyboard.c had an integer overflow if
     k_ascii is called several times in a row, aka CID-b86dab054059.
     (bnc#1172775).
   - CVE-2019-20810: go7007_snd_init in drivers/media/usb/go7007/snd-go7007.c
     in the Linux kernel did not call snd_card_free for a failure path, which
     causes a memory leak, aka CID-9453264ef586 (bnc#1172458).

   The following non-security bugs were fixed:

   - Drivers: hv: Change flag to write log level in panic msg to false
     (bsc#1170618).
   - ibmvnic: Do not process device remove during device reset (bsc#1065729).
   - ibmvnic: Do not process reset during or after device removal
     (bsc#1149652 ltc#179635).
   - ibmvnic: Flush existing work items before device removal (bsc#1065729).
   - ibmvnic: Harden device login requests (bsc#1170011 ltc#183538).
   - ibmvnic: Skip fatal error reset after passive init (bsc#1171078
     ltc#184239).
   - ibmvnic: Unmap DMA address of TX descriptor buffers after use
     (bsc#1146351 ltc#180726).
   - ibmvnic: continue to init in CRQ reset returns H_CLOSED (bsc#1173280
     ltc#185369).
   - intel_idle: Graceful probe failure when MWAIT is disabled (bsc#1174115).
   - mm, vmstat: reduce zone->lock holding time by /proc/pagetypeinfo
     (bsc#1164910).
   - net/ibmvnic: Fix missing { in __ibmvnic_reset (bsc#1149652 ltc#179635).
   - net/ibmvnic: free reset work of removed device from queue (bsc#1149652
     ltc#179635).
   - net/ibmvnic: prevent more than one thread from running in reset
     (bsc#1152457 ltc#174432).
   - net/ibmvnic: unlock rtnl_lock in reset so linkwatch_event can run
     (bsc#1152457 ltc#174432).
   - udp: drop corrupt packets earlier to avoid data corruption (bsc#1173658).
