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 ... [Please see the references for more information on the vulnerabilities]");
