Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7607-1 advisory.

 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)

 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:

 - SCSI subsystem;

 - Network file system (NFS) client;

 - NILFS2 file system;

 - File systems infrastructure;

 - Memory management;

 - Bluetooth subsystem;

 - Network traffic control;

 - USB sound devices; (CVE-2024-50116, CVE-2021-47576, CVE-2024-53197, CVE-2024-46787, CVE-2025-37798, CVE-2024-49958, CVE-2021-47260, CVE-2025-37932, CVE-2022-49909)

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.

Solution

Update the affected kernel package.
