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

  - A flaw was found in the way Linux kernel KVM hypervisor     before 4.18 emulated instructions such as     sgdt/sidt/fxsave/fxrstor. It did not check current     privilege(CPL) level while emulating unprivileged     instructions. An unprivileged guest user/process could     use this flaw to potentially escalate privileges inside     guest. (CVE-2018-10853)

  - A flaw was found in the Linux Kernel where an attacker     may be able to have an uncontrolled read to kernel-     memory from within a vm guest. A race condition between     connect() and close() function may allow an attacker     using the AF_VSOCK protocol to gather a 4 byte     information leak or possibly intercept or corrupt     AF_VSOCK messages destined to other clients.
    (CVE-2018-14625)

  - drivers/infiniband/core/ucma.c in the Linux kernel     through 4.17.11 allows ucma_leave_multicast to access a     certain data structure after a cleanup step in     ucma_process_join, which allows attackers to cause a     denial of service (use-after-free). (CVE-2018-14734)

  - arch/x86/kernel/paravirt.c in the Linux kernel before     4.18.1 mishandles certain indirect calls, which makes it     easier for attackers to conduct Spectre-v2 attacks     against paravirtual guests. (CVE-2018-15594)

  - A flaw was found in the Linux kernel's NFS     implementation, all versions 3.x and all versions 4.x up     to 4.20. An attacker, who is able to mount an exported     NFS filesystem, is able to trigger a null pointer     dereference by using an invalid NFS sequence. This can     panic the machine and deny access to the NFS server. Any     outstanding disk writes to the NFS server will be lost.
    (CVE-2018-16871)

  - A flaw was found in the Linux kernel's NFS41+ subsystem.
    NFS41+ shares mounted in different network namespaces at     the same time can make bc_svc_process() use wrong back-     channel IDs and cause a use-after-free vulnerability.
    Thus a malicious container user can cause a host kernel     memory corruption and a system panic. Due to the nature     of the flaw, privilege escalation cannot be fully ruled     out. (CVE-2018-16884)

  - Since Linux kernel version 3.2, the mremap() syscall     performs TLB flushes after dropping pagetable locks. If     a syscall such as ftruncate() removes entries from the     pagetables of a task that is in the middle of mremap(),     a stale TLB entry can remain for a short time that     permits access to a physical page after it has been     released back to the page allocator and reused. This is     fixed in the following kernel versions: 4.9.135,     4.14.78, 4.18.16, 4.19. (CVE-2018-18281)

  - In the hidp_process_report in bluetooth, there is an     integer overflow. This could lead to an out of bounds     write with no additional execution privileges needed.
    User interaction is not needed for exploitation.
    Product: Android Versions: Android kernel Android ID:
    A-65853588 References: Upstream kernel. (CVE-2018-9363)

  - In pppol2tp_connect, there is possible memory corruption     due to a use after free. This could lead to local     escalation of privilege with System execution privileges     needed. User interaction is not needed for exploitation.
    Product: Android. Versions: Android kernel. Android ID:
    A-38159931. (CVE-2018-9517)

  - Insufficient input validation in Kernel Mode Driver in     Intel(R) i915 Graphics for Linux before version 5.0 may     allow an authenticated user to potentially enable     escalation of privilege via local access.
    (CVE-2019-11085)

  - The coredump implementation in the Linux kernel before     5.0.10 does not use locking or other mechanisms to     prevent vma layout or vma flags changes while it runs,     which allows local users to obtain sensitive     information, cause a denial of service, or possibly have     unspecified other impact by triggering a race condition     with mmget_not_zero or get_task_mm calls. This is     related to fs/userfaultfd.c, mm/mmap.c,     fs/proc/task_mmu.c, and     drivers/infiniband/core/uverbs_main.c. (CVE-2019-11599)

  - An issue was discovered in the Linux kernel before     5.0.7. A NULL pointer dereference can occur when     megasas_create_frame_pool() fails in     megasas_alloc_cmds() in     drivers/scsi/megaraid/megaraid_sas_base.c. This causes a     Denial of Service, related to a use-after-free.
    (CVE-2019-11810)

  - An issue was discovered in the Linux kernel before     5.0.4. There is a use-after-free upon attempted read     access to /proc/ioports after the ipmi_si module is     removed, related to drivers/char/ipmi/ipmi_si_intf.c,     drivers/char/ipmi/ipmi_si_mem_io.c, and     drivers/char/ipmi/ipmi_si_port_io.c. (CVE-2019-11811)

  - fs/ext4/extents.c in the Linux kernel through 5.1.2 does     not zero out the unused memory region in the extent tree     block, which might allow local users to obtain sensitive     information by reading uninitialized data in the     filesystem. (CVE-2019-11833)

  - A heap address information leak while using     L2CAP_GET_CONF_OPT was discovered in the Linux kernel     before 5.1-rc1. (CVE-2019-3459)

  - A heap data infoleak in multiple locations including     L2CAP_PARSE_CONF_RSP was found in the Linux kernel     before 5.1-rc1. (CVE-2019-3460)

  - A flaw was found in the Linux kernel's vfio interface     implementation that permits violation of the user's     locked memory limit. If a device is bound to a vfio     driver, such as vfio-pci, and the local attacker is     administratively granted ownership of the device, it may     cause a system memory exhaustion and thus a denial of     service (DoS). Versions 3.10, 4.14 and 4.18 are     vulnerable. (CVE-2019-3882)

  - An infinite loop issue was found in the vhost_net kernel     module in Linux Kernel up to and including v5.1-rc6,     while handling incoming packets in handle_rx(). It could     occur if one end sends packets faster than the other end     can process them. A guest user, maybe remote one, could     use this flaw to stall the vhost_net kernel thread,     resulting in a DoS scenario. (CVE-2019-3900)

  - The mincore() implementation in mm/mincore.c in the     Linux kernel through 4.19.13 allowed local attackers to     observe page cache access patterns of other processes on     the same system, potentially allowing sniffing of secret     information. (Fixing this affects the output of the     fincore program.) Limited remote exploitation may be     possible, as demonstrated by latency differences in     accessing public files from an Apache HTTP Server.
    (CVE-2019-5489)
