The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5791-2 advisory.

    It was discovered that a race condition existed in the Android Binder IPC subsystem 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-2022-20421)

    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)

    It was discovered that the Intel 740 frame buffer driver in the Linux kernel contained a divide by zero     vulnerability. A local attacker could use this to cause a denial of service (system crash).
    (CVE-2022-3061)

    It was discovered that the sound subsystem in the Linux kernel contained a race condition in some     situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-3303)

    Gwnaun Jung discovered that the SFB packet scheduling implementation 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-2022-3586)

    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)

    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 EFI capsule loader 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-2022-40307)

    Zheng Wang and Zhuorao Yang discovered that the RealTek RTL8712U wireless driver 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-2022-4095)

    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)

    Jann Horn discovered a race condition existed in the Linux kernel when unmapping VMAs in certain     situations, resulting in possible use-after-free vulnerabilities. A local attacker could possibly use this     to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-39188)

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.
