The remote Ubuntu 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5687-1 advisory.

    It was discovered that the SUNRPC RDMA protocol implementation in the Linux kernel did not properly     calculate the header size of a RPC message payload. A local attacker could use this to expose sensitive     information (kernel memory). (CVE-2022-0812)

    Moshe Kol, Amit Klein and Yossi Gilad discovered that the IP implementation in the Linux kernel did not     provide sufficient randomization when calculating port offsets. An attacker could possibly use this to     expose sensitive information. (CVE-2022-1012, CVE-2022-32296)

    Duoming Zhou discovered that race conditions existed in the timer handling implementation of the Linux     kernel's Rose X.25 protocol layer, resulting in use-after-free vulnerabilities. A local attacker could use     this to cause a denial of service (system crash). (CVE-2022-2318)

    Roger Pau Monn discovered that the Xen virtual block driver in the Linux kernel did not properly     initialize memory pages to be used for shared communication with the backend. A local attacker could use     this to expose sensitive information (guest kernel memory). (CVE-2022-26365)

    Roger Pau Monn discovered that the Xen paravirtualization frontend in the Linux kernel did not properly     initialize memory pages to be used for shared communication with the backend. A local attacker could use     this to expose sensitive information (guest kernel memory). (CVE-2022-33740)

    It was discovered that the Xen paravirtualization frontend in the Linux kernel incorrectly shared     unrelated data when communicating with certain backends. A local attacker could use this to cause a denial     of service (guest crash) or expose sensitive information (guest kernel memory). (CVE-2022-33741,     CVE-2022-33742)

    Oleksandr Tyshchenko discovered that the Xen paravirtualization platform in the Linux kernel on ARM     platforms contained a race condition in certain situations. An attacker in a guest VM could use this to     cause a denial of service in the host OS. (CVE-2022-33744)

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.
