The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5113-1 advisory.

    It was discovered that a race condition existed in the Atheros Ath9k WiFi driver in the Linux kernel. An     attacker could possibly use this to expose sensitive information (WiFi network traffic). (CVE-2020-3702)

    Alois Wohlschlager discovered that the overlay file system in the Linux kernel did not restrict private     clones in some situations. An attacker could use this to expose sensitive information. (CVE-2021-3732)

    It was discovered that the btrfs file system in the Linux kernel did not properly handle removing a non-     existent device id. An attacker with CAP_SYS_ADMIN could use this to cause a denial of service.
    (CVE-2021-3739)

    It was discovered that the Qualcomm IPC Router protocol implementation in the Linux kernel did not     properly validate metadata in some situations. A local attacker could use this to cause a denial of     service (system crash) or expose sensitive information. (CVE-2021-3743)

    It was discovered that the virtual terminal (vt) device implementation in the Linux kernel contained a     race condition in its ioctl handling that led to an out-of-bounds read vulnerability. A local attacker     could possibly use this to expose sensitive information. (CVE-2021-3753)

    It was discovered that the BPF subsystem in the Linux kernel contained an integer overflow in its hash     table implementation. A local attacker could use this to cause a denial of service (system crash) or     possibly execute arbitrary code. (CVE-2021-38166)

    It was discovered that the ext4 file system in the Linux kernel contained a race condition when writing     xattrs to an inode. A local attacker could use this to cause a denial of service or possibly gain     administrative privileges. (CVE-2021-40490)

    It was discovered that the 6pack network protocol driver in the Linux kernel did not properly perform     validation checks. A privileged attacker could use this to cause a denial of service (system crash) or     execute arbitrary code. (CVE-2021-42008)

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.
