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-6681-2 advisory.

    Wenqing Liu discovered that the f2fs file system implementation in the Linux kernel did not properly     validate inode types while performing garbage collection. An attacker could use this to construct a     malicious f2fs image that, when mounted and operated on, could cause a denial of service (system crash).
    (CVE-2021-44879)

    It was discovered that the DesignWare USB3 for Qualcomm SoCs driver in the Linux kernel did not properly     handle certain error conditions during device registration. A local attacker could possibly use this to     cause a denial of service (system crash). (CVE-2023-22995)

    Bien Pham discovered that the netfiler subsystem in the Linux kernel contained a race condition, leading     to a use-after-free vulnerability. A local user could use this to cause a denial of service (system crash)     or possibly execute arbitrary code. (CVE-2023-4244)

    It was discovered that a race condition existed in the Bluetooth subsystem of the Linux kernel, 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-2023-51779)

    It was discovered that a race condition existed in the ATM (Asynchronous Transfer Mode) subsystem of the     Linux kernel, 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-2023-51780)

    It was discovered that a race condition existed in the Rose X.25 protocol implementation in the Linux     kernel, 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-2023-51782)

    Alon Zahavi discovered that the NVMe-oF/TCP subsystem of the Linux kernel did not properly handle connect     command payloads in certain situations, leading to an out-of-bounds read vulnerability. A remote attacker     could use this to expose sensitive information (kernel memory). (CVE-2023-6121)

    It was discovered that the VirtIO subsystem in the Linux kernel did not properly initialize memory in some     situations. A local attacker could use this to possibly expose sensitive information (kernel memory).
    (CVE-2024-0340)

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.
