The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5529-1 advisory.

    It was discovered that the Atheros ath9k wireless device driver in the Linux kernel did not properly     handle some error conditions, 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-2022-1679)

    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)

    Qiuhao Li, Gaoning Pan, and Yongkang Jia discovered that the KVM hypervisor implementation in the Linux     kernel did not properly handle an illegal instruction in a guest, resulting in a null pointer dereference.
    An attacker in a guest VM could use this to cause a denial of service (system crash) in the host OS.
    (CVE-2022-1852)

    Gerald Lee discovered that the NTFS file system implementation in the Linux kernel did not properly handle     certain error conditions, leading to a use- after-free vulnerability. A local attacker could use this to     cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2022-1973)

    It was discovered that the netfilter subsystem in the Linux kernel contained a buffer overflow in certain     situations. A local attacker could use this to cause a denial of service (system crash) or possibly     execute arbitrary code. (CVE-2022-2078)

    It was discovered that some Intel processors did not completely perform cleanup actions on multi-core     shared buffers. A local attacker could possibly use this to expose sensitive information. (CVE-2022-21123)

    It was discovered that some Intel processors did not completely perform cleanup actions on     microarchitectural fill buffers. A local attacker could possibly use this to expose sensitive information.
    (CVE-2022-21125)

    It was discovered that some Intel processors did not properly perform cleanup during specific special     register write operations. A local attacker could possibly use this to expose sensitive information.
    (CVE-2022-21166)

    It was discovered that the virtio RPMSG bus driver in the Linux kernel contained a double-free     vulnerability in certain error conditions. A local attacker could possibly use this to cause a denial of     service (system crash). (CVE-2022-34494, CVE-2022-34495)

    Minh Yuan discovered that the floppy disk driver in the Linux kernel contained a race condition, leading     to 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-2022-1652)

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.
