The remote Ubuntu 14.04 LTS / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6926-2 advisory.

     discovered that the NFC Controller Interface (NCI) implementation in the Linux kernel did not     properly handle certain memory allocation failure conditions, leading to a null pointer dereference     vulnerability. A local attacker could use this to cause a denial of service (system crash).
    (CVE-2023-46343)

    It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel when     modifying certain settings values through debugfs. A privileged local attacker could use this to cause a     denial of service. (CVE-2024-24857, CVE-2024-24858, CVE-2024-24859)

    Chenyuan Yang discovered that the Unsorted Block Images (UBI) flash device volume management subsystem did     not properly validate logical eraseblock sizes in certain situations. An attacker could possibly use this     to cause a denial of service (system crash). (CVE-2024-25739)

    Supraja Sridhara, Benedict Schlter, Mark Kuhne, Andrin Bertschi, and Shweta Shinde discovered that the     Confidential Computing framework in the Linux kernel for x86 platforms did not properly handle 32-bit     emulation on TDX and SEV. An attacker with access to the VMM could use this to cause a denial of service     (guest crash) or possibly execute arbitrary code. (CVE-2024-25744)

    Several security issues were discovered in the Linux kernel. An attacker could possibly use these to     compromise the system. This update corrects flaws in the following subsystems:

    - GPU drivers;

    - HID subsystem;

    - I2C subsystem;

    - MTD block device drivers;

    - Network drivers;

    - TTY drivers;

    - USB subsystem;

    - File systems infrastructure;

    - F2FS file system;

    - SMB network file system;

    - BPF subsystem;

    - B.A.T.M.A.N. meshing protocol;

    - Bluetooth subsystem;

    - Networking core;

    - IPv4 networking;

    - IPv6 networking;

    - Netfilter;

    - Unix domain sockets;

    - AppArmor security module; (CVE-2024-26884, CVE-2024-26882, CVE-2024-26923, CVE-2024-26840,     CVE-2023-52435, CVE-2024-35984, CVE-2024-26886, CVE-2023-52752, CVE-2023-52436, CVE-2024-36016,     CVE-2024-26857, CVE-2024-36902, CVE-2023-52443, CVE-2024-35997, CVE-2024-35982, CVE-2023-52469,     CVE-2024-27020, CVE-2024-35978, CVE-2024-26934, CVE-2024-27013, CVE-2023-52449, CVE-2024-26901,     CVE-2023-52444, CVE-2023-52620)

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.
