Ubuntu 18.04 LTS / 20.04 LTS : Linux kernel vulnerabilities (USN-7173-2)

high Nessus Plugin ID 213299

Synopsis

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

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7173-2 advisory.

 Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this vulnerability to cause a denial of service. (CVE-2022-38096)

 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:

 - GPU drivers;

 - Network drivers;

 - SCSI subsystem;

 - Ext4 file system;

 - Bluetooth subsystem;

 - Memory management;

 - Amateur Radio drivers;

 - Network traffic control;

 - Sun RPC protocol;

 - VMware vSockets driver; (CVE-2023-52821, CVE-2024-40910, CVE-2024-43892, CVE-2024-49967, CVE-2024-50264, CVE-2024-36952, CVE-2024-38553, CVE-2021-47101, CVE-2021-47001, CVE-2024-35965, CVE-2024-35963, CVE-2024-35966, CVE-2024-35967, CVE-2024-53057, CVE-2024-38597)

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
