"According to the versions of the kernel packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - A memory leak in the af9005_identify_state() function
    in drivers/media/usb/dvb-usb/af9005.c in the Linux
    kernel through 5.3.9 allows attackers to cause a denial
    of service (memory consumption), aka
    CID-2289adbfa559.(CVE-2019-18809)

  - A memory leak in the dwc3_pci_probe() function in
    drivers/usb/dwc3/dwc3-pci.c in the Linux kernel through
    5.3.9 allows attackers to cause a denial of service
    (memory consumption) by triggering
    platform_device_add_properties() failures, aka
    CID-9bbfceea12a8.(CVE-2019-18813)

  - A memory leak in the ql_alloc_large_buffers() function
    in drivers/net/ethernet/qlogic/qla3xxx.c in the Linux
    kernel before 5.3.5 allows local users to cause a
    denial of service (memory consumption) by triggering
    pci_dma_mapping_error() failures, aka
    CID-1acb8f2a7a9f.(CVE-2019-18806)

  - drivers/net/wireless/intel/iwlwifi/pcie/trans.c in the
    Linux kernel 5.2.14 does not check the alloc_workqueue
    return value, leading to a NULL pointer
    dereference.(CVE-2019-16234)

  - Insufficient access control in the Intel(R)
    PROSet/Wireless WiFi Software driver before version
    21.10 may allow an unauthenticated user to potentially
    enable denial of service via adjacent
    access.(CVE-2019-0136)

  - An issue was discovered in net/wireless/nl80211.c in
    the Linux kernel through 5.2.17. It does not check the
    length of variable elements in a beacon head, leading
    to a buffer overflow.(CVE-2019-16746)

  - In the Linux kernel through 5.3.2,
    cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c
    does not reject a long SSID IE, leading to a Buffer
    Overflow.(CVE-2019-17133)

  - rtl_p2p_noa_ie in
    drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux
    kernel through 5.3.6 lacks a certain upper-bound check,
    leading to a buffer overflow.(CVE-2019-17666)

  - 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)

  - ax25_create in net/ax25/af_ax25.c in the AF_AX25
    network module in the Linux kernel through 5.3.2 does
    not enforce CAP_NET_RAW, which means that unprivileged
    users can create a raw socket, aka
    CID-0614e2b73768.(CVE-2019-17052)

  - ieee802154_create in net/ieee802154/socket.c in the
    AF_IEEE802154 network module in the Linux kernel
    through 5.3.2 does not enforce CAP_NET_RAW, which means
    that unprivileged users can create a raw socket, aka
    CID-e69dbd4619e7.(CVE-2019-17053)

  - atalk_create in net/appletalk/ddp.c in the AF_APPLETALK
    network module in the Linux kernel through 5.3.2 does
    not enforce CAP_NET_RAW, which means that unprivileged
    users can create a raw socket, aka
    CID-6cc03e8aa36c.(CVE-2019-17054)

  - base_sock_create in drivers/isdn/mISDN/socket.c in the
    AF_ISDN network module in the Linux kernel through
    5.3.2 does not enforce CAP_NET_RAW, which means that
    unprivileged users can create a raw socket, aka
    CID-b91ee4aa2a21.(CVE-2019-17055)

  - llcp_sock_create in net/nfc/llcp_sock.c in the AF_NFC
    network module in the Linux kernel through 5.3.2 does
    not enforce CAP_NET_RAW, which means that unprivileged
    users can create a raw socket, aka
    CID-3a359798b176.(CVE-2019-17056)

This update provides the corresponding updates for the Linux Hardware
Enablement (HWE) kernel from Ubuntu 19.10 for Ubuntu 18.04 LTS.

It was discovered that a heap-based buffer overflow existed in the
Marvell WiFi-Ex Driver for the Linux kernel. A physically proximate
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2019-14895, CVE-2019-14901)

It was discovered that a heap-based buffer overflow existed in the
Marvell Libertas WLAN Driver for the Linux kernel. A physically
proximate attacker could use this to cause a denial of service (system
crash) or possibly execute arbitrary code. (CVE-2019-14896,
CVE-2019-14897)

It was discovered that the Fujitsu ES network device driver for the
Linux kernel did not properly check for errors in some situations,
leading to a NULL pointer dereference. A local attacker could use this
to cause a denial of service. (CVE-2019-16231)

Anthony Steinhauser discovered that the Linux kernel did not properly
perform Spectre_RSB mitigations to all processors for PowerPC
architecture systems in some situations. A local attacker could use
this to expose sensitive information. (CVE-2019-18660)

It was discovered that the Mellanox Technologies Innova driver in the
Linux kernel did not properly deallocate memory in certain failure
conditions. A local attacker could use this to cause a denial of
service (kernel memory exhaustion). (CVE-2019-19045)

It was discovered that the Intel WiMAX 2400 driver in the Linux kernel
did not properly deallocate memory in certain situations. A local
attacker could use this to cause a denial of service (kernel memory
exhaustion). (CVE-2019-19051)

It was discovered that Geschwister Schneider USB CAN interface driver
in the Linux kernel did not properly deallocate memory in certain
failure conditions. A physically proximate attacker could use this to
cause a denial of service (kernel memory exhaustion). (CVE-2019-19052)

It was discovered that the netlink-based 802.11 configuration
interface in the Linux kernel did not deallocate memory in certain
error conditions. A local attacker could possibly use this to cause a
denial of service (kernel memory exhaustion). (CVE-2019-19055)

It was discovered that the event tracing subsystem of the Linux kernel
did not properly deallocate memory in certain error conditions. A
local attacker could use this to cause a denial of service (kernel
memory exhaustion). (CVE-2019-19072)

It was discovered that the driver for memoryless force-feedback input
devices in the Linux kernel contained a use-after-free vulnerability.
A physically proximate attacker could possibly use this to cause a
denial of service (system crash) or execute arbitrary code.
(CVE-2019-19524)

It was discovered that the Microchip CAN BUS Analyzer driver in the
Linux kernel contained a use-after-free vulnerability on device
disconnect. A physically proximate attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2019-19529)

It was discovered that the PEAK-System Technik USB driver in the Linux
kernel did not properly sanitize memory before sending it to the
device. A physically proximate attacker could use this to expose
sensitive information (kernel memory). (CVE-2019-19534)

It was discovered that the DesignWare USB3 controller driver in the
Linux kernel did not properly deallocate memory in some error
conditions. A local attacker could possibly use this to cause a denial
of service (memory exhaustion). (CVE-2019-18813).
