The remote Ubuntu 18.04 LTS / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5539-1 advisory.

    It was discovered that the implementation of the 6pack and mkiss protocols in the Linux kernel did not     handle detach events properly in some situations, leading to a use-after-free vulnerability. A local     attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-1195)

    Duoming Zhou discovered that the AX.25 amateur radio protocol implementation in the Linux kernel did not     handle detach events properly in some situations. A local attacker could possibly use this to cause a     denial of service (system crash) or execute arbitrary code. (CVE-2022-1199)

    Duoming Zhou discovered race conditions in the AX.25 amateur radio protocol implementation in the Linux     kernel during device detach operations. A local attacker could possibly use this to cause a denial of     service (system crash). (CVE-2022-1204)

    Duoming Zhou discovered race conditions in the AX.25 amateur radio protocol implementation in the Linux     kernel, leading to use-after-free vulnerabilities. A local attacker could possibly use this to cause a     denial of service (system crash). (CVE-2022-1205)

    Yongkang Jia discovered that the KVM hypervisor implementation in the Linux kernel did not properly handle     guest TLB mapping invalidation requests in some situations. An attacker in a guest VM could use this to     cause a denial of service (system crash) in the host OS. (CVE-2022-1789)

    It was discovered that the 8 Devices USB2CAN interface implementation in the Linux kernel did not properly     handle certain error conditions, leading to a double-free. A local attacker could possibly use this to     cause a denial of service (system crash). (CVE-2022-28388)

    Minh Yuan discovered that the floppy driver in the Linux kernel contained a race condition in some     situations, leading to 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-2022-33981)

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.
