______________________________________________________________________________

   An update that solves 29 vulnerabilities and has 7 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-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
   https://www.suse.com/support/kb/

   - 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
   https://www.suse.com/support/kb/

   - 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-2019-16234: iwlwifi pcie driver did not check the alloc_workqueue
     return value, leading to a NULL pointer dereference. (bsc#1150452).
   - CVE-2019-16232: Fix a potential NULL pointer dereference in the Marwell
     libertas driver (bsc#1150465).
   - CVE-2019-17052: ax25_create in the AF_AX25 network module in the Linux
     kernel did not enforce CAP_NET_RAW, which meant that unprivileged users     could create a raw socket, aka CID-0614e2b73768. (bnc#1152779)
   - CVE-2019-17055: base_sock_create in the AF_ISDN network module in the
     Linux kernel did not enforce CAP_NET_RAW, which means that unprivileged
     users can create a raw socket,  aka CID-b91ee4aa2a21. (bnc#1152782)
   - CVE-2019-17054: atalk_create in the AF_APPLETALK network module in the
     Linux kernel did not enforce CAP_NET_RAW, which means that unprivileged
     users can create a raw socket, aka CID-6cc03e8aa36c. (bnc#1152786)
   - CVE-2019-17133: cfg80211 wireless extension did not reject a long SSID
     IE, leading to a Buffer Overflow (bsc#1153158).
   - CVE-2019-17053: ieee802154_create in the AF_IEEE802154 network module in
     the Linux kernel did not enforce CAP_NET_RAW, which means that
     unprivileged users could create a raw socket, aka CID-e69dbd4619e7.
     (bnc#1152789)
   - 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-2019-15291: There was a NULL pointer dereference caused by a
     malicious USB device in the flexcop_usb_probe function. (bnc#1146540)
   - CVE-2019-15807: There was a memory leak in the SAS expander driver when
     SAS expander discovery fails. This could cause a denial of service.
     (bnc#1148938)
   - CVE-2019-14821: An out-of-bounds access issue was found in the way Linux
     the kernel's KVM hypervisor implemented the Coalesced MMIO write
     operation. It operated on an MMIO ring buffer 'struct
     kvm_coalesced_mmio' object, wherein write indices value could be
     supplied by a host user-space process. 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 service
     or potentially escalating privileges on the system. (bnc#1151350)
   - CVE-2019-15505: The Linux kernel had an out-of-bounds read via crafted
     USB device traffic (which may have been remote via usbip or usbredir).
     (bnc#1147122)
   - CVE-2019-14835: A buffer overflow flaw was found in the way Linux
     kernel's vhost functionality that translates virtqueue buffers to IOVs,
     logged the buffer descriptors during migration. A privileged guest user
     able to pass descriptors with invalid length to the host when migration
     is underway, could have used this flaw to increase their privileges on
     the host. (bnc#1150112)
   - CVE-2019-15216: There was a NULL pointer dereference caused by a
     malicious USB device in the drivers/usb/misc/yurex.c driver.
     (bnc#1146361)
   - CVE-2019-9456: In the Android kernel in Pixel C USB monitor driver there
     was a possible OOB write due to a missing bounds check. This could lead
     to local escalation of privilege with System execution privileges
     needed. User interaction was not needed for exploitation. (bnc#1150025)
   - CVE-2019-15927: An out-of-bounds access existed in the function
     build_audio_procunit in the file sound/usb/mixer.c. (bnc#1149522)
   - CVE-2019-15902:  Misuse of the upstream "x86/ptrace: Fix possible
     spectre-v1 in ptrace_get_debugreg()" commit reintroduced the Spectre
     vulnerability that it 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-2019-15219: There was a NULL pointer dereference caused by a
     malicious USB device in the drivers/usb/misc/sisusbvga/sisusb.c driver.
     (bnc#1146524)
   - CVE-2017-18509: An issue was discovered in net/ipv6/ip6mr.c in the Linux
     kernel By setting a specific socket option, an attacker could control a
     pointer in kernel land and cause an inet_csk_listen_stop general
     protection fault, or potentially execute arbitrary code under certain
     circumstances. The issue could be triggered as root (e.g., inside a
     default LXC container or with the CAP_NET_ADMIN capability)
     or after namespace unsharing. This occurred because sk_type and protocol
      were not checked in the appropriate part of the ip6_mroute_* functions.
      (bnc#1145477)
   - CVE-2019-15212: There was a double-free caused by a malicious USB device
     in the drivers/usb/misc/rio500.c driver. (bnc#1146391)
   - CVE-2019-15292: There was a use-after-free in atalk_proc_exit.
     (bnc#1146678)
   - CVE-2019-15217: There was a NULL pointer dereference caused by a
     malicious USB device in the drivers/media/usb/zr364xx/zr364xx.c driver.
     (bnc#1146547)
   - CVE-2018-20976: A use after free was discovered in fs/xfs/xfs_super.c,
     related to xfs_fs_fill_super failure. (bnc#1146285)
   - CVE-2017-18551: There was an out of bounds write in the function
     i2c_smbus_xfer_emulated. (bnc#1146163)
   - CVE-2019-15118: check_input_term in sound/usb/mixer.c mishandled
     recursion, leading to kernel stack exhaustion. (bnc#1145922)

     lfence in userspace interrupt exit paths

   - kvm: VMX: export PFEC.P bit on ept (bsc#1117665).
   - kvm: vmx, svm: always run with EFER.NXE=1 when shadow paging is active
     (bsc#1117665).
   - kvm: x86: make FNAME(fetch) and __direct_map more similar (bsc#1117665).
   - kvm: x86: mmu: Apply global mitigations knob to ITLB_MULTIHIT
     (bnc#1117665).
