The version of cifs-utils installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2025-2312 advisory.

  - A flaw was found in cifs-utils. When trying to obtain Kerberos credentials, the cifs.upcall program from     the cifs-utils package makes an upcall to the wrong namespace in containerized environments. This issue     May lead to disclosing sensitive data from the host's Kerberos credentials cache. (CVE-2025-2312)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Ubuntu 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7384-1 advisory.

    Michael Randrianantenaina discovered that the Bluetooth driver in the Linux Kernel contained an improper     access control vulnerability. A nearby attacker could use this to connect a rougue device and possibly     execute arbitrary code. (CVE-2024-8805)

    Attila Szsz discovered that the HFS+ file system implementation in the Linux Kernel contained a heap     overflow vulnerability. An attacker could use a specially crafted file system image that, when mounted,     could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2025-0927)

    It was discovered that the CIFS network file system implementation in the Linux kernel did not properly     verify the target namespace when handling upcalls. An attacker could use this to expose sensitive     information. (CVE-2025-2312)
