Bluetooth Mesh Provisioning in the Bluetooth Mesh profile 1.0 and 1.0.1 may permit a nearby device, reflecting the authentication evidence from a Provisioner, to complete authentication without possessing the AuthValue, and potentially acquire a NetKey and AppKey.

The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - kernel: Authvalue leak in Bluetooth Mesh Provisioning (CVE-2020-26559)

  - bluez: BlueZ allows physically proximate attackers to cause a denial of service because malformed and     invalid capabilities can be processed in profiles/audio/avdtp.c (CVE-2022-39177)

  - Pairing in Bluetooth Core v5.2 and earlier may permit an unauthenticated attacker to acquire credentials     with two pairing devices via adjacent access when the unauthenticated user initiates different pairing     methods in each peer device and an end-user erroneously completes both pairing procedures with the MITM     using the confirmation number of one peer as the passkey of the other. An adjacent, unauthenticated     attacker could be able to initiate any Bluetooth operation on either attacked device exposed by the     enabled Bluetooth profiles. This exposure may be limited when the user must authorize certain access     explicitly, but so long as a user assumes that it is the intended remote device requesting permissions,     device-local protections may be weakened. (CVE-2020-10134)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 9 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - kernel: impersonation attack in Bluetooth Mesh Provisioning (CVE-2020-26560)

  - bluez: BlueZ allows physically proximate attackers to cause a denial of service because malformed and     invalid capabilities can be processed in profiles/audio/avdtp.c (CVE-2022-39177)

  - A vulnerability classified as problematic has been found in Linux Kernel. Affected is the function     read_50_controller_cap_complete of the file tools/mgmt-tester.c of the component BlueZ. The manipulation     of the argument cap_len leads to null pointer dereference. It is recommended to apply a patch to fix this     issue. VDB-211086 is the identifier assigned to this vulnerability. (CVE-2022-3563)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.
