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.

vendor_unpatched cve-2025-2312: Unpatched CVEs for Debian Linux (cve-2025-2312)

The remote Ubuntu 24.04 LTS / 24.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7448-1 advisory.

    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)

    Several security issues were discovered in the Linux kernel. An attacker could possibly use these to     compromise the system. This update corrects flaws in the following subsystems:

    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)
