    ______________________________________________________________________________
    
       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/doc/?id=7023735
    
       - 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/doc/?id=7024251
    
       - 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)
    
       The following non-security bugs were fixed:
    
       - add a missing lfence in kernel error entry and remove a superfluous
         lfence in userspace interrupt exit paths
       - Documentation: Add ITLB_MULTIHIT documentation (bnc#1117665).

       - kvm: MMU: fast invalidate all pages (bsc1117665).
       - 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).
       - mm/readahead.c: fix readahead failure for memoryless NUMA nodes and
         limit readahead pages (bsc#1143327).
       - mm: use only per-device readahead limit (bsc#1143327).
