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-5851-1 advisory.

    It was discovered that a memory leak existed in the Unix domain socket implementation of the Linux kernel.
    A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2022-3543)

    It was discovered that the Bluetooth HCI implementation in the Linux kernel did not properly deallocate     memory in some situations. An attacker could possibly use this cause a denial of service (memory     exhaustion). (CVE-2022-3619)

    It was discovered that the hugetlb implementation 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) or expose     sensitive information (kernel memory). (CVE-2022-3623)

    It was discovered that the Broadcom FullMAC USB WiFi driver in the Linux kernel did not properly perform     bounds checking in some situations. A physically proximate attacker could use this to craft a malicious     USB device that when inserted, could cause a denial of service (system crash) or possibly execute     arbitrary code. (CVE-2022-3628)

    It was discovered that a use-after-free vulnerability existed in the Bluetooth stack in the Linux kernel.
    A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary     code. (CVE-2022-3640)

    It was discovered that a race condition existed in the SMSC UFX USB driver implementation in the Linux     kernel, leading to a use-after-free vulnerability. A physically proximate attacker could use this to cause     a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-41849)

    It was discovered that a race condition existed in the Roccat HID 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-2022-41850)

    Tams Koczka discovered that the Bluetooth L2CAP implementation in the Linux kernel did not properly     initialize memory in some situations. A physically proximate attacker could possibly use this to expose     sensitive information (kernel memory). (CVE-2022-42895)

    Arnaud Gatignol, Quentin Minster, Florent Saudel and Guillaume Teissier discovered that the KSMBD     implementation in the Linux kernel did not properly validate user-supplied data in some situations. An     authenticated attacker could use this to cause a denial of service (system crash), expose sensitive     information (kernel memory) or possibly execute arbitrary code. (CVE-2022-47940)

    It was discovered that a race condition existed in the qdisc implementation 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-2023-0590)

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.
