The remote Ubuntu 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4226-1 advisory.

Michael Hanselmann discovered that the CIFS implementation in the Linux kernel did not sanitize paths     returned by an SMB server. An attacker controlling an SMB server could use this to overwrite arbitrary     files. (CVE-2019-10220)

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)

It was discovered that the QLogic Fibre Channel driver in the Linux kernel did not properly check for     error, leading to a NULL pointer dereference. A local attacker could possibly use this to cause a denial     of service (system crash). (CVE-2019-16233)

Nicolas Waisman discovered that the WiFi driver stack in the Linux kernel did not properly validate SSID     lengths. A physically proximate attacker could use this to cause a denial of service (system crash).
(CVE-2019-17133)

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 VirtualBox guest driver implementation in the Linux kernel did not properly     deallocate memory in certain error conditions. A local attacker could use this to cause a denial of     service (memory exhaustion). (CVE-2019-19048)

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 ADIS16400 IIO IMU Driver for the Linux kernel did not properly deallocate     memory in certain error conditions. A local attacker could use this to cause a denial of service (memory     exhaustion). (CVE-2019-19060)

It was discovered that the Intel OPA Gen1 Infiniband Driver for the Linux kernel did not properly     deallocate memory in certain error conditions. A local attacker could use this to cause a denial of     service (memory exhaustion). (CVE-2019-19065)

It was discovered that the AMD Audio Coprocessor driver for the Linux kernel did not properly deallocate     memory in certain error conditions. A local attacker with the ability to load modules could use this to     cause a denial of service (memory exhaustion). (CVE-2019-19067)

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 Cascoda CA8210 SPI 802.15.4 wireless controller driver for the Linux kernel did     not properly deallocate memory in certain error conditions. A local attacker could use this to cause a     denial of service (memory exhaustion). (CVE-2019-19075)

It was discovered that the AMD Display Engine Driver in the Linux kernel did not properly deallocate     memory in certain error conditions. A local attack could use this to cause a denial of service (memory     exhaustion). (CVE-2019-19083)

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 NXP PN533 NFC USB driver in the Linux kernel did not properly free resources     after a late probe error, leading to a use- after-free vulnerability. A physically proximate attacker     could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
(CVE-2019-19526)

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 multiple USB HID device drivers in the Linux kernel did not properly validate     device metadata on attachment, leading to out-of- bounds writes. A physically proximate attacker could use     this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-19532)

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 in some situations the fair scheduler in the Linux kernel did not permit a process     to use its full quota time slice. A local attacker could use this to cause a denial of service.
(CVE-2019-19922)

It was discovered that the binder IPC implementation in the Linux kernel did not properly perform bounds     checking in some situations, leading to an out-of-bounds write. A local attacker could use this to cause a     denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-2214)

Nicolas Waisman discovered that the Chelsio T4/T5 RDMA Driver for the Linux kernel performed DMA from a     kernel stack. A local attacker could use this to cause a denial of service (system crash).
(CVE-2019-17075)

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)
