   An update that solves 13 vulnerabilities and has 43 fixes
   is now available.

Description:

   The SUSE Linux Enterprise 12 SP2 kernel was updated to receive various
   security and bugfixes.

   The following security bugs were fixed:

   - CVE-2018-19985: The function hso_probe read if_num from the USB device
     (as an u8) and used it without a length check to index an array,
     resulting in an OOB memory read in hso_probe or hso_get_config_data that
     could be used by local attackers (bnc#1120743).
   - CVE-2018-16884: NFS41+ shares mounted in different network namespaces at
     the same time can make bc_svc_process() use wrong back-channel IDs and
     cause a use-after-free vulnerability. Thus a malicious container user
     can cause a host kernel memory corruption and a system panic. Due to the
     nature of the flaw, privilege escalation cannot be fully ruled out
     (bnc#1119946).
   - CVE-2018-20169: The USB subsystem mishandled size checks during the
     reading of an extra descriptor, related to __usb_get_extra_descriptor in
     drivers/usb/core/usb.c (bnc#1119714).
   - CVE-2018-9568: In sk_clone_lock of sock.c, there is a possible memory
     corruption due to type confusion. This could lead to local escalation of
     privilege with no additional execution privileges needed. User
     interaction is not needed for exploitation. (bnc#1118319).
   - CVE-2018-16862: A security flaw was found in a way that the cleancache
     subsystem clears an inode after the final file truncation (removal). The
     new file created with the same inode may contain leftover pages from
     cleancache and the old file data instead of the new one (bnc#1117186).
   - CVE-2018-19824: A local user could exploit a use-after-free in the ALSA
     driver by supplying a malicious USB Sound device (with zero interfaces)
     that is mishandled in usb_audio_probe in sound/usb/card.c (bnc#1118152).
   - CVE-2018-18281: The mremap() syscall performs TLB flushes after dropping
     pagetable locks. If a syscall such as ftruncate() removes entries from
     the pagetables of a task that is in the middle of mremap(), a stale TLB
     entry can remain for a short time that permits access to a physical page
     after it has been released back to the page allocator and reused.
     (bnc#1113769).
   - CVE-2018-18710: An information leak in cdrom_ioctl_select_disc in
     drivers/cdrom/cdrom.c could be used by local attackers to read kernel
     memory because a cast from unsigned long to int interferes with bounds
     checking. This is similar to CVE-2018-10940 and CVE-2018-16658
     (bnc#1113751).
   - CVE-2018-18690: A local attacker able to set attributes on an xfs
     filesystem could make this filesystem non-operational until the next
     mount by triggering an unchecked error condition during an xfs attribute
     change, because xfs_attr_shortform_addname in fs/xfs/libxfs/xfs_attr.c
     mishandled ATTR_REPLACE operations with conversion of an attr from short
     to long form (bnc#1105025).
   - CVE-2018-18386: drivers/tty/n_tty.c allowed local attackers (who are
     able to access pseudo terminals) to hang/block further usage of any
     pseudo terminal devices due to an EXTPROC versus ICANON confusion in
     TIOCINQ (bnc#1094825).
   - CVE-2018-9516: In hid_debug_events_read of drivers/hid/hid-debug.c,
     there is a possible out of bounds write due to a missing bounds check.
     This could lead to local escalation of privilege with System execution
     privileges needed. User interaction is not needed for exploitation.
     (bnc#1108498).
   - CVE-2019-3459, CVE-2019-3460: The Blutooth stack suffered from two
     remote information leak vulnerabilities in the code that handles
     incoming L2cap configuration packets (bsc#1120758).

     (bsc#1116027).
