   An update that solves 8 vulnerabilities and has 11 fixes is
   now available.

Description:


   The SUSE Linux Enterprise 11 SP3 kernel was updated to receive various
   security and bugfixes.

   The following security bugs were fixed:

   - CVE-2018-14634: Prevent integer overflow in create_elf_tables that
     allowed a local attacker to exploit this vulnerability via a SUID-root
     binary and obtain full root privileges (bsc#1108912).
   - CVE-2018-10940: The cdrom_ioctl_media_changed function allowed local
     attackers to use a incorrect bounds check in the CDROM driver
     CDROM_MEDIA_CHANGED ioctl to read out kernel memory (bsc#1092903)
   - CVE-2018-16658: Prevent information leak in cdrom_ioctl_drive_status
     that could have been used by local attackers to read kernel memory
     (bnc#1107689)
   - CVE-2018-6555: The irda_setsockopt function allowed local users to cause
     a denial of service (ias_object use-after-free and system crash) or
     possibly have unspecified other impact via an AF_IRDA socket
     (bnc#1106511)
   - CVE-2018-6554: Prevent memory leak in the irda_bind function that
     allowed local users to cause a denial of service (memory consumption) by
     repeatedly binding an AF_IRDA socket (bnc#1106509)
   - CVE-2018-15572: The spectre_v2_select_mitigation function did not always
     fill RSB upon a context switch, which made it easier for attackers to
     conduct userspace-userspace spectreRSB attacks (bnc#1102517)
   - CVE-2018-10902: Protect against concurrent access to prevent double
     realloc (double free) in snd_rawmidi_input_params() and
     snd_rawmidi_output_status(). A malicious local attacker could have used
     this for privilege escalation (bnc#1105322).
   - CVE-2018-14734: ucma_leave_multicast accessed a certain data structure
     after a cleanup step in ucma_process_join, which allowed attackers to
     cause a denial
     of service (use-after-free) (bsc#1103119).

   The following non-security bugs were fixed:

   - KVM: VMX: Work around kABI breakage in 'enum vmx_l1d_flush_state'
     (bsc#1106369).
   - KVM: VMX: fixes for vmentry_l1d_flush module parameter (bsc#1106369).
   - KVM: x86: Free vmx_msr_bitmap_longmode while kvm_init failed
     (bsc#1104367).
   - Refresh patches.xen/xen3-x86-l1tf-04-protect-PROT_NONE-ptes.patch
     (bsc#1105100).
   - kabi: x86/speculation/l1tf: Increase l1tf memory limit for Nehalem+
     (bnc#1105536).
   - kabi: x86/speculation/l1tf: Increase l1tf memory limit for Nehalem+
     (bnc#1105536).
   - ptrace: fix PTRACE_LISTEN race corrupting task->state (bnc#1107001).
   - rpm/kernel-docs.spec.in: Expand kernel tree directly from sources
     (bsc#1057199)
   - x86, l1tf: Protect PROT_NONE PTEs against speculation fixup
     (bnc#1104684, bnc#1104818).
   - x86/speculation/l1tf: Fix off-by-one error when warning that system has
     too much RAM (bnc#1105536).
   - x86/speculation/l1tf: Fix overflow in l1tf_pfn_limit() on 32bit
     (bnc#1087081).
   - x86/speculation/l1tf: Increase l1tf memory limit for Nehalem+
     (bnc#1105536).
   - x86/speculation/l1tf: Suggest what to do on systems with too much RAM
     (bnc#1105536).
   - xen x86/speculation/l1tf: Fix off-by-one error when warning that system
     has too much RAM (bnc#1105536).
   - xen x86/speculation/l1tf: Increase l1tf memory limit for Nehalem+
     (bnc#1105536).
   - xen, x86, l1tf: Protect PROT_NONE PTEs against speculation fixup
     (bnc#1104684, bnc#1104818).
   - xen: x86/speculation/l1tf: Fix overflow in l1tf_pfn_limit() on 32bit
     (bnc#1087081).
