The openSUSE Leap 15.0 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

  - CVE-2019-0154: An unprotected read access to i915     registers has been fixed that could have been abused to     facilitate a local denial-of-service attack.
    (bsc#1135966)

  - CVE-2019-0155: A privilege escalation vulnerability has     been fixed in the i915 module that allowed batch buffers     from user mode to gain super user privileges.
    (bsc#1135967)

  - CVE-2019-16231: drivers/net/fjes/fjes_main.c did not     check the alloc_workqueue return value, leading to a     NULL pointer dereference (bnc#1150466).

  - CVE-2019-18805: There was a net/ipv4/tcp_input.c signed     integer overflow in tcp_ack_update_rtt() when userspace     writes a very large integer to     /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading to a denial     of service or possibly unspecified other impact, aka     CID-19fad20d15a6 (bnc#1156187).

  - CVE-2019-17055: base_sock_create in     drivers/isdn/mISDN/socket.c in the AF_ISDN network     module did not enforce CAP_NET_RAW, which means that     unprivileged users can create a raw socket, aka     CID-b91ee4aa2a21 (bnc#1152782).

  - CVE-2019-16995: A memory leak exits in     hsr_dev_finalize() in net/hsr/hsr_device.c, if     hsr_add_port fails to add a port, which may cause denial     of service, aka CID-6caabe7f197d (bnc#1152685).

  - 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=7024251

  - CVE-2019-16233: drivers/scsi/qla2xxx/qla_os.c did not     check the alloc_workqueue return value, leading to a     NULL pointer dereference (bnc#1150457).

  - 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.

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel-rt packages installed that are affected by multiple vulnerabilities:

  - The bnep_sock_ioctl function in     net/bluetooth/bnep/sock.c in the Linux kernel before     2.6.39 does not ensure that a certain device field ends     with a '\0' character, which allows local users to     obtain potentially sensitive information from kernel     stack memory, or cause a denial of service (BUG and     system crash), via a BNEPCONNADD command.
    (CVE-2011-1079)

  - An issue was discovered in fs/gfs2/rgrp.c in the Linux     kernel before 4.8. A use-after-free is caused by the     functions gfs2_clear_rgrpd and read_rindex_entry.
    (CVE-2016-10905)

  - An issue was discovered in     drivers/scsi/aacraid/commctrl.c in the Linux kernel     before 4.13. There is potential exposure of kernel stack     memory because aac_get_hba_info does not initialize the     hbainfo structure. (CVE-2017-18550)

  - An issue was discovered in the Linux kernel before     4.14.11. A double free may be caused by the function     allocate_trace_buffer in the file kernel/trace/trace.c.
    (CVE-2017-18595)

  - Improper invalidation for page table updates by a     virtual guest operating system for multiple Intel(R)     Processors may allow an authenticated user to     potentially enable denial of service of the host system     via local access. (CVE-2018-12207)

  - An issue was discovered in the Linux kernel before 4.20.
    There is a race condition in smp_task_timedout() and     smp_task_done() in drivers/scsi/libsas/sas_expander.c,     leading to a use-after-free. (CVE-2018-20836)

  - An issue was discovered in the Linux kernel before     4.18.7. In create_qp_common in     drivers/infiniband/hw/mlx5/qp.c, mlx5_ib_create_qp_resp     was never initialized, resulting in a leak of stack     memory to userspace. (CVE-2018-20855)

  - An issue was discovered in fs/xfs/xfs_super.c in the     Linux kernel before 4.18. A use after free exists,     related to xfs_fs_fill_super failure. (CVE-2018-20976)

  - In the tun subsystem in the Linux kernel before 4.13.14,     dev_get_valid_name is not called before     register_netdevice. This allows local users to cause a     denial of service (NULL pointer dereference and panic)     via an ioctl(TUNSETIFF) call with a dev name containing     a / character. This is similar to CVE-2013-4343.
    (CVE-2018-7191)

  - Insufficient access control in subsystem for Intel (R)     processor graphics in 6th, 7th, 8th and 9th Generation     Intel(R) Core(TM) Processor Families; Intel(R)     Pentium(R) Processor J, N, Silver and Gold Series;
    Intel(R) Celeron(R) Processor J, N, G3900 and G4900     Series; Intel(R) Atom(R) Processor A and E3900 Series;
    Intel(R) Xeon(R) Processor E3-1500 v5 and v6 and E-2100     Processor Families may allow an authenticated user to     potentially enable denial of service via local access.
    (CVE-2019-0154)

  - Insufficient access control in a subsystem for Intel (R)     processor graphics in 6th, 7th, 8th and 9th Generation     Intel(R) Core(TM) Processor Families; Intel(R)     Pentium(R) Processor J, N, Silver and Gold Series;
    Intel(R) Celeron(R) Processor J, N, G3900 and G4900     Series; Intel(R) Atom(R) Processor A and E3900 Series;
    Intel(R) Xeon(R) Processor E3-1500 v5 and v6, E-2100 and     E-2200 Processor Families; Intel(R) Graphics Driver for     Windows before 26.20.100.6813 (DCH) or 26.20.100.6812     and before 21.20.x.5077 (aka15.45.5077), i915 Linux     Driver for Intel(R) Processor Graphics before versions     5.4-rc7, 5.3.11, 4.19.84, 4.14.154, 4.9.201, 4.4.201 may     allow an authenticated user to potentially enable     escalation of privilege via local access.
    (CVE-2019-0155)

  - TSX Asynchronous Abort condition on some CPUs utilizing     speculative execution may allow an authenticated user to     potentially enable information disclosure via a side     channel with local access. (CVE-2019-11135)

  - The Linux kernel before 5.1-rc5 allows page->_refcount     reference count overflow, with resultant use-after-free     issues, if about 140 GiB of RAM exists. This is related     to fs/fuse/dev.c, fs/pipe.c, fs/splice.c,     include/linux/mm.h, include/linux/pipe_fs_i.h,     kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can     occur with FUSE requests. (CVE-2019-11487)

  - The do_hidp_sock_ioctl function in     net/bluetooth/hidp/sock.c in the Linux kernel before     5.0.15 allows a local user to obtain potentially     sensitive information from kernel stack memory via a     HIDPCONNADD command, because a name field may not end     with a '\0' character. (CVE-2019-11884)

  - ** DISPUTED ** An issue was discovered in     drm_load_edid_firmware in     drivers/gpu/drm/drm_edid_load.c in the Linux kernel     through 5.1.5. There is an unchecked kstrdup of fwstr,     which might allow an attacker to cause a denial of     service (NULL pointer dereference and system crash).
    NOTE: The vendor disputes this issues as not being a     vulnerability because kstrdup() returning NULL is     handled sufficiently and there is no chance for a NULL     pointer dereference. (CVE-2019-12382)

  - An issue was discovered in the Linux kernel before     5.2.3. There is a use-after-free caused by a malicious     USB device in the drivers/media/usb/dvb-usb/dvb-usb-     init.c driver. (CVE-2019-15213)

  - An issue was discovered in xfs_setattr_nonsize in     fs/xfs/xfs_iops.c in the Linux kernel through 5.2.9. XFS     partially wedges when a chgrp fails on account of being     out of disk quota. xfs_setattr_nonsize is failing to     unlock the ILOCK after the xfs_qm_vop_chown_reserve call     fails. This is primarily a local DoS attack vector, but     it might result as well in remote DoS if the XFS     filesystem is exported for instance via NFS.
    (CVE-2019-15538)

  - In the Linux kernel before 5.1.13, there is a memory     leak in drivers/scsi/libsas/sas_expander.c when SAS     expander discovery fails. This will cause a BUG and     denial of service. (CVE-2019-15807)

  - An issue was discovered in the Linux kernel before     5.0.1. There is a memory leak in     register_queue_kobjects() in net/core/net-sysfs.c, which     will cause denial of service. (CVE-2019-15916)

  - An issue was discovered in the Linux kernel before     5.0.4. The 9p filesystem did not protect i_size_write()     properly, which causes an i_size_read() infinite loop     and denial of service on SMP systems. (CVE-2019-16413)

  - An issue was discovered in write_tpt_entry in     drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel     through 5.3.2. The cxgb4 driver is directly calling     dma_map_single (a DMA function) from a stack variable.
    This could allow an attacker to trigger a Denial of     Service, exploitable if this driver is used on an     architecture for which this stack/DMA interaction has     security relevance. (CVE-2019-17075)

  - The SCTP socket buffer used by a userspace application     is not accounted by the cgroups subsystem. An attacker     can use this flaw to cause a denial of service attack.
    Kernel 3.10.x and 4.18.x branches are believed to be     vulnerable. (CVE-2019-3874)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
