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-7186-2 advisory.

    Andy Nguyen discovered that the Bluetooth L2CAP implementation in the Linux kernel contained a type-     confusion error. A physically proximate remote attacker could use this to cause a denial of service     (system crash) or possibly execute arbitrary code. (CVE-2020-12351)

    Andy Nguyen discovered that the Bluetooth A2MP implementation in the Linux kernel did not properly     initialize memory in some situations. A physically proximate remote attacker could use this to expose     sensitive information (kernel memory). (CVE-2020-12352)

    Andy Nguyen discovered that the Bluetooth HCI event packet parser in the Linux kernel did not properly     handle event advertisements of certain sizes, leading to a heap-based buffer overflow. A physically     proximate remote attacker could use this to cause a denial of service (system crash) or possibly execute     arbitrary code. (CVE-2020-24490)

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.

In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: RFCOMM: FIX possible deadlock in rfcomm_sk_state_change rfcomm_sk_state_change attempts to use sock_lock so it must never be called with it locked but rfcomm_sock_ioctl always attempt to lock it.

This plugin only works with Tenable.ot.
