The remote Ubuntu 16.04 ESM / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5727-2 advisory.

    It was discovered that a race condition existed in the instruction emulator of the Linux kernel on Arm     64-bit systems. A local attacker could use this to cause a denial of service (system crash).
    (CVE-2022-20422)

    It was discovered that the KVM implementation in the Linux kernel did not properly handle virtual CPUs     without APICs in certain situations. A local attacker could possibly use this to cause a denial of service     (host system crash). (CVE-2022-2153)

    Hao Sun and Jiacheng Xu discovered that the NILFS file system implementation in the Linux kernel contained     a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system     crash) or possibly execute arbitrary code. (CVE-2022-2978)

    Abhishek Shah discovered a race condition in the PF_KEYv2 implementation in the Linux kernel. A local     attacker could use this to cause a denial of service (system crash) or possibly expose sensitive     information (kernel memory). (CVE-2022-3028)

    It was discovered that the IDT 77252 ATM PCI device driver in the Linux kernel did not properly remove any     pending timers during device exit, resulting in a use-after-free vulnerability. A local attacker could     possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-3635)

    It was discovered that the Netlink Transformation (XFRM) subsystem in the Linux kernel contained a     reference counting error. A local attacker could use this to cause a denial of service (system crash).
    (CVE-2022-36879)

    Xingyuan Mo and Gengjia Chen discovered that the Promise SuperTrak EX storage controller driver in the     Linux kernel did not properly handle certain structures. A local attacker could potentially use this to     expose sensitive information (kernel memory). (CVE-2022-40768)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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