The remote Ubuntu 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5861-1 advisory.

    It was discovered that the NFSD implementation in the Linux kernel did not properly handle some RPC     messages, leading to a buffer overflow. A remote attacker could use this to cause a denial of service     (system crash) or possibly execute arbitrary code. (CVE-2022-43945)

    Tams Koczka discovered that the Bluetooth L2CAP handshake implementation in the Linux kernel contained     multiple use-after-free vulnerabilities. A physically proximate attacker could use this to cause a denial     of service (system crash) or possibly execute arbitrary code. (CVE-2022-42896)

    It was discovered that an out-of-bounds write vulnerability existed in the Video for Linux 2 (V4L2)     implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system     crash) or possibly execute arbitrary code. (CVE-2022-20369)

    Pawan Kumar Gupta, Alyssa Milburn, Amit Peled, Shani Rehana, Nir Shildan and Ariel Sabba discovered that     some Intel processors with Enhanced Indirect Branch Restricted Speculation (eIBRS) did not properly handle     RET instructions after a VM exits. A local attacker could potentially use this to expose sensitive     information. (CVE-2022-26373)

    David Leadbeater discovered that the netfilter IRC protocol tracking implementation in the Linux Kernel     incorrectly handled certain message payloads in some situations. A remote attacker could possibly use this     to cause a denial of service or bypass firewall filtering. (CVE-2022-2663)

    Johannes Wikner and Kaveh Razavi discovered that for some AMD x86-64 processors, the branch predictor     could by mis-trained for return instructions in certain circumstances. A local attacker could possibly use     this to expose sensitive information. (CVE-2022-29900)

    Johannes Wikner and Kaveh Razavi discovered that for some Intel x86-64 processors, the Linux kernel's     protections against speculative branch target injection attacks were insufficient in some circumstances. A     local attacker could possibly use this to expose sensitive information. (CVE-2022-29901)

    It was discovered that the Xen netback driver in the Linux kernel did not properly handle packets     structured in certain ways. An attacker in a guest VM could possibly use this to cause a denial of service     (host NIC availability). (CVE-2022-3643)

    It was discovered that the NILFS2 file system implementation in the Linux kernel did not properly     deallocate memory in certain error conditions. An attacker could use this to cause a denial of service     (memory exhaustion). (CVE-2022-3646)

    Khalid Masum discovered that the NILFS2 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 or possibly execute arbitrary code. (CVE-2022-3649)

    Hyunwoo Kim discovered that an integer overflow vulnerability existed in the PXA3xx graphics driver in the     Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash).
    (CVE-2022-39842)

    It was discovered that a race condition existed in the SMSC UFX USB driver implementation in the Linux     kernel, leading to a use-after-free vulnerability. A physically proximate attacker could use this to cause     a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-41849)

    It was discovered that a race condition existed in the Roccat HID driver 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-2022-41850)

    It was discovered that the USB monitoring (usbmon) component in the Linux kernel did not properly set     permissions on memory mapped in to user space processes. A local attacker could use this to cause a denial     of service (system crash) or possibly execute arbitrary code. (CVE-2022-43750)

    It was discovered that an integer overflow vulnerability existed in the Bluetooth subsystem in the Linux     kernel. A physically proximate attacker could use this to cause a denial of service (system crash).
    (CVE-2022-45934)

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.
