    An update that solves one vulnerability and has 8 fixes is now available.

    Description:


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

    The following security bug was fixed:

    - CVE-2018-3665: Prevent disclosure of FPU registers (including XMM and
    AVX registers) between processes. These registers might contain
    encryption keys when doing SSE accelerated AES enc/decryption
    (bsc#1087086)

    The following non-security bugs were fixed:

    - KVM: x86: Sync back MSR_IA32_SPEC_CTRL to VCPU data structure
    (bsc#1096242, bsc#1096281).
    - Xen counterparts of eager FPU implementation.
    - x86/boot: Fix early command-line parsing when partial word matches
    (bsc#1096140).
    - x86/bugs: spec_ctrl must be cleared from cpu_caps_set when being
    disabled (bsc#1096140).
    - xen/x86/CPU: Check speculation control CPUID bit (bsc#1068032).
    - xen/x86/CPU: Sync CPU feature flags late (bsc#1075994 bsc#1075091).
    - xen/x86/cpu: Factor out application of forced CPU caps (bsc#1075994
    bsc#1075091).
    - xen/x86/cpu: Fix bootup crashes by sanitizing the argument of the
    'clearcpuid=' command-line option (bsc#1065600).
    - xen/x86/entry/64: Do not use IST entry for #BP stack (bsc#1087088).
    - xen/x86/entry: Use IBRS on entry to kernel space (bsc#1068032).
    - xen/x86/idle: Toggle IBRS when going idle (bsc#1068032).
    - xen/x86/kaiser: Move feature detection up (bsc#1068032).
