The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5667-1 advisory.

    Selim Enes Karaduman discovered that a race condition existed in the General notification queue     implementation of 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-2022-1882)

    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)

    Eric Biggers discovered that a use-after-free vulnerability existed in the io_uring subsystem in the Linux     kernel. A local attacker could possibly use this to cause a denial of service (system crash) or possibly     execute arbitrary code. (CVE-2022-3176)

    It was discovered that the Netlink Transformation (XFRM) subsystem in the Linux kernel contained a     reference counting error. A local attacker could use this to cause a denial of service (system crash).
    (CVE-2022-36879)

    Jann Horn discovered that the KVM subsystem in the Linux kernel did not properly handle TLB flush     operations in some situations. A local attacker in a guest VM could use this to cause a denial of service     (guest crash) or possibly execute arbitrary code in the guest kernel. (CVE-2022-39189)

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.
