An update that solves 13 vulnerabilities and has four fixes
is now available.

Description:


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

The following security bugs were fixed:

- CVE-2018-3620: Local attackers on baremetal systems could use
speculative code patterns on hyperthreaded processors to read data
present in the L1 Datacache used by other hyperthreads on the same CPU
core, potentially leaking sensitive data. (bnc#1087081).
- CVE-2018-3646: Local attackers in virtualized guest systems could use
speculative code patterns on hyperthreaded processors to read data
present in the L1 Datacache used by other hyperthreads on the same CPU
core, potentially leaking sensitive data, even from other virtual
machines or the host system. (bnc#1089343).
- CVE-2018-1000204: A malformed SG_IO ioctl issued for a SCSI device could
lead to a local kernel information leak manifesting in up to
approximately 1000 memory pages copied to the userspace. The problem has
limited scope as non-privileged users usually have no permissions to
access SCSI device files. (bnc#1096728).
- CVE-2018-13053: The alarm_timer_nsleep function in
kernel/time/alarmtimer.c had an integer overflow via a large relative
timeout because ktime_add_safe is not used (bnc#1099924).
- CVE-2018-13406: An integer overflow in the uvesafb_setcmap function in
drivers/video/fbdev/uvesafb.c could result in local attackers being able
to crash the kernel or potentially elevate privileges because
kmalloc_array is not used (bnc#1098016 bnc#1100418).
- CVE-2016-8405: An information disclosure vulnerability in kernel
components including the ION subsystem, Binder, USB driver and
networking subsystem could enable a local malicious application to
access data outside of its permission levels. (bnc#1099942).
- CVE-2018-5814: Multiple race condition errors when handling probe,
disconnect, and rebind operations could be exploited to trigger a
use-after-free condition or a NULL pointer dereference by sending
multiple USB over IP packets (bnc#1096480).
- CVE-2018-12233: In the ea_get function in fs/jfs/xattr.c a memory
corruption bug in JFS can be triggered by calling setxattr twice with
two different extended attribute names on the same file. This
vulnerability can be triggered by an unprivileged user with the ability
to create files and execute programs. (bnc#1097234).
- CVE-2017-13305: A information disclosure vulnerability in the Upstream
kernel encrypted-keys. (bnc#1094353).
- CVE-2018-1130: A null pointer dereference in dccp_write_xmit() function
in net/dccp/output.c allowed a local user to cause a denial of service
by a number of certain crafted system calls (bnc#1092904).
- CVE-2018-1068: A flaw was found in the implementation of 32-bit syscall
interface for bridging. This allowed a privileged user to arbitrarily
write to a limited range of kernel memory (bnc#1085107).
- CVE-2018-5803: An error in the "_sctp_make_chunk()" function
(net/sctp/sm_make_chunk.c) when handling SCTP packets length could be
exploited to cause a kernel crash (bnc#1083900).
- CVE-2018-7492: A NULL pointer dereference was found in the
net/rds/rdma.c __rds_rdma_map() function allowed local attackers to
cause a system panic and a denial-of-service, related to RDS_GET_MR and
RDS_GET_MR_FOR_DEST (bnc#1082962).

The following non-security bugs were fixed:

- cpu/hotplug: Add sysfs state interface (bsc#1089343).
- cpu/hotplug: Provide knobs to control SMT (bsc#1089343).
- cpu/hotplug: Split do_cpu_down() (bsc#1089343).
- disable-prot_none_mitigation.patch: disable prot_none native mitigation
(bnc#1104684)
- fix pgd underflow (bnc#1104475) custom walk_page_range rework was
incorrect and could underflow pgd if the given range was below a first
vma.
- slab: introduce kmalloc_array() (bsc#909361).
- x86/apic: Ignore secondary threads if nosmt=force (bsc#1089343).
- x86/cpu/AMD: Do not check CPUID max ext level before parsing SMP info
(bsc#1089343).
- x86/cpu/AMD: Evaluate smp_num_siblings early (bsc#1089343).
- x86/cpu/AMD: Move TOPOEXT reenablement before reading smp_num_siblings
(bsc#1089343).
- x86/cpu/AMD: Remove the pointless detect_ht() call (bsc#1089343).
- x86/cpu/common: Provide detect_ht_early() (bsc#1089343).
- x86/cpu/intel: Evaluate smp_num_siblings early (bsc#1089343).
- x86/cpu: Remove the pointless CPU printout (bsc#1089343).
- x86/cpu/topology: Provide detect_extended_topology_early() (bsc#1089343).
- x86/smpboot: Do not use smp_num_siblings in __max_logical_packages
calculation (bsc#1089343).
- x86/smp: Provide topology_is_primary_thread() (bsc#1089343).
- x86/topology: Add topology_max_smt_threads() (bsc#1089343).
- x86/topology: Provide topology_smt_supported() (bsc#1089343).
- xen/x86/cpu/common: Provide detect_ht_early() (bsc#1089343).
- xen/x86/cpu: Remove the pointless CPU printout (bsc#1089343).
- xen/x86/cpu/topology: Provide detect_extended_topology_early()
(bsc#1089343).
- x86/mm: Simplify p[g4um]d_page() macros (bnc#1087081, bnc#1104684).
