   An update that solves 8 vulnerabilities and has 73 fixes is
   now available.


   The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various
   security and bugfixes.

   The following security bugs were fixed:

   - CVE-2016-10741: fs/xfs/xfs_aops.c allowed local users to cause a denial
     of service (system crash) because there is a race condition between
     direct and memory-mapped I/O (associated with a hole) that is handled
     with BUG_ON instead of an I/O failure (bnc#1114920 bnc#1124010).
   - CVE-2017-18360: In change_port_settings in drivers/usb/serial/io_ti.c
     local users could cause a denial of service by division-by-zero in the
     serial device layer by trying to set very high baud rates (bnc#1123706).
   - 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-2018-19407: The vcpu_scan_ioapic function in arch/x86/kvm/x86.c
     allowed local users to cause a denial of service (NULL pointer
     dereference and BUG) via crafted system calls that reach a situation
     where ioapic is uninitialized (bnc#1116841).
   - 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-2018-19985: 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-2018-20169: 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-2019-7222: A information leak in exception handling in KVM could be
     used to expose host memory to guests. (bnc#1124735).
