The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5161-1 advisory.

    Ilja Van Sprundel discovered that the SCTP implementation in the Linux kernel did not properly perform     size validations on incoming packets in some situations. An attacker could possibly use this to expose     sensitive information (kernel memory). (CVE-2021-3655)

    It was discovered that the AMD Cryptographic Coprocessor (CCP) driver in the Linux kernel did not properly     deallocate memory in some error conditions. A local attacker could use this to cause a denial of service     (memory exhaustion). (CVE-2021-3744, CVE-2021-3764)

    It was discovered that the Aspeed Low Pin Count (LPC) Bus Controller implementation in the Linux kernel     did not properly perform boundary checks in some situations, allowing out-of-bounds write access. A local     attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. In     Ubuntu, this issue only affected systems running armhf kernels. (CVE-2021-42252)

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.
