  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 SP1 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:
CVE-2018-12207: Untrusted virtual machines on Intel CPUs could exploit a
 race condition in the Instruction Fetch Unit of the Intel CPU to cause a
 Machine Exception during Page Size Change, causing the CPU core to be
 non-functional.

The Linux Kernel KVM hypervisor was adjusted to avoid page size changes in executable pages by splitting / merging huge pages into small pages as needed. More information can be found on [link moved to references] CVE-2019-11135: Aborting an asynchronous TSX operation on Intel CPUs
 with Transactional Memory support could be used to facilitate
 sidechannel information leaks out of microarchitectural buffers, similar
 to the previously described 'Microarchitectural Data Sampling' attack.

The Linux kernel was supplemented with the option to disable TSX operation altogether (requiring CPU Microcode updates on older systems) and better flushing of microarchitectural buffers (VERW).

The set of options available is described in our TID at [link moved to references] CVE-2019-16233: drivers/scsi/qla2xxx/qla_os.c did not check the
 alloc_workqueue return value, leading to a NULL pointer dereference.
 (bsc#1150457).
CVE-2019-10220: Added sanity checks on the pathnames passed to the user
 space. (bsc#1144903).
CVE-2019-16232: Fix a potential NULL pointer dereference in the Marwell
 libertas driver (bsc#1150465).
CVE-2019-16234: iwlwifi pcie driver did not check the alloc_workqueue
 return value, leading to a NULL pointer dereference. (bsc#1150452).
CVE-2019-17055: The AF_ISDN network module in the Linux kernel did not
 enforce CAP_NET_RAW, which meant that unprivileged users could create a
 raw socket (bnc#1152782).
CVE-2019-17056: The AF_NFC network module did not enforce CAP_NET_RAW,
 which meant that unprivileged users could create a raw socket
 (bsc#1152788).
CVE-2019-16413: The 9p filesystem did not protect i_size_write()
 properly, which caused an i_size_read() infinite loop and denial of
 service on SMP systems (bnc#1151347).
CVE-2019-15902: A backporting issue was discovered that re-introduced
 the Spectre vulnerability it had aimed to eliminate. This occurred
 because the backport process depends on cherry picking specific commits,
 and because two (correctly ordered) code lines were swapped
 (bnc#1149376).
CVE-2019-15291: Fixed a NULL pointer dereference issue that could be
 caused by a malicious USB device (bnc#11465).
CVE-2019-15807: Fixed a memory leak in the SCSI module that could be
 abused to cause denial of service (bnc#1148938).
CVE-2019-14821: An out-of-bounds access issue was fixed in the kernel's
 KVM hypervisor. An unprivileged host user or process with access to
 '/dev/kvm' device could use this flaw to crash the host kernel,
 resulting in a denial of ... [Please see the references for more information on the vulnerabilities]");
