Description

Security update for the Linux Kernel 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).
