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-5384-1 advisory.

    It was discovered that the UDF file system implementation in the Linux kernel could attempt to dereference     a null pointer in some situations. An attacker could use this to construct a malicious UDF image that,     when mounted and operated on, could cause a denial of service (system crash). (CVE-2022-0617)

    Lyu Tao discovered that the NFS implementation in the Linux kernel did not properly handle requests to     open a directory on a regular file. A local attacker could use this to expose sensitive information     (kernel memory). (CVE-2022-24448)

    It was discovered that the YAM AX.25 device driver in the Linux kernel did not properly deallocate memory     in some error conditions. A local privileged attacker could use this to cause a denial of service (kernel     memory exhaustion). (CVE-2022-24959)

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.

    Brendan Dolan-Gavitt discovered that the aQuantia AQtion Ethernet device driver in the Linux kernel did     not properly validate meta-data coming from the device. A local attacker who can control an emulated     device can use this to cause a denial of service (system crash) or possibly execute arbitrary code.
