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-5467-1 advisory.

    It was discovered that the Linux kernel did not properly restrict access to the kernel debugger when     booted in secure boot environments. A privileged attacker could use this to bypass UEFI Secure Boot     restrictions. (CVE-2022-21499)

    Aaron Adams discovered that the netfilter subsystem in the Linux kernel did not properly handle the     removal of stateful expressions in some situations, leading to a use-after-free vulnerability. A local     attacker could use this to cause a denial of service (system crash) or execute arbitrary code.
    (CVE-2022-1966)

    It was discovered that the SCTP protocol implementation in the Linux kernel did not properly verify VTAGs     in some situations. A remote attacker could possibly use this to cause a denial of service (connection     disassociation). (CVE-2021-3772)

    Eric Biederman discovered that the cgroup process migration implementation in the Linux kernel did not     perform permission checks correctly in some situations. A local attacker could possibly use this to gain     administrative privileges. (CVE-2021-4197)

    Jann Horn discovered that the FUSE file system in the Linux kernel contained 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-2022-1011)

    Qiuhao Li, Gaoning Pan and Yongkang Jia discovered that the KVM implementation in the Linux kernel did not     properly perform guest page table updates in some situations. An attacker in a guest vm could possibly use     this to crash the host OS. (CVE-2022-1158)

    Duoming Zhou discovered that the 6pack protocol implementation in the Linux kernel did not handle detach     events properly in some situations, leading to a use-after-free vulnerability. A local attacker could use     this to cause a denial of service (system crash). (CVE-2022-1198)

    It was discovered that the PF_KEYv2 implementation in the Linux kernel did not properly initialize kernel     memory in some situations. A local attacker could use this to expose sensitive information (kernel     memory). (CVE-2022-1353)

    It was discovered that the implementation of X.25 network protocols in the Linux kernel did not terminate     link layer sessions properly. A local attacker could possibly use this to cause a denial of service     (system crash). (CVE-2022-1516)

    Demi Marie Obenour and Simon Gaiser discovered that several Xen para- virtualization device frontends did     not properly restrict the access rights of device backends. An attacker could possibly use a malicious Xen     backend to gain access to memory pages of a guest VM or cause a denial of service in the guest.
    (CVE-2022-23036, CVE-2022-23037, CVE-2022-23038, CVE-2022-23039, CVE-2022-23040, CVE-2022-23041,     CVE-2022-23042)

    It was discovered that the USB Gadget file system interface in the Linux kernel contained 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-2022-24958)

    It was discovered that the USB SR9700 ethernet device driver for the Linux kernel did not properly     validate the length of requests from the device. A physically proximate attacker could possibly use this     to expose sensitive information (kernel memory). (CVE-2022-26966)

     discovered that the 802.2 LLC type 2 driver in the Linux kernel did not properly perform     reference counting in some error conditions. A local attacker could use this to cause a denial of service.
    (CVE-2022-28356)

    It was discovered that the Microchip CAN BUS Analyzer interface implementation in the Linux kernel did not     properly handle certain error conditions, leading to a double-free. A local attacker could possibly use     this to cause a denial of service (system crash). (CVE-2022-28389)

    It was discovered that the EMS CAN/USB interface implementation in the Linux kernel contained a double-     free vulnerability when handling certain error conditions. A local attacker could use this to cause a     denial of service (memory exhaustion). (CVE-2022-28390)

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.
