Ubuntu 20.04 LTS / 22.04 LTS : Linux kernel vulnerabilities (USN-7179-1)

high Nessus Plugin ID 213300

Synopsis

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

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7179-1 advisory.

 Andy Nguyen discovered that the Bluetooth L2CAP implementation in the Linux kernel contained a type- confusion error. A physically proximate remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-12351)

 Andy Nguyen discovered that the Bluetooth A2MP implementation in the Linux kernel did not properly initialize memory in some situations. A physically proximate remote attacker could use this to expose sensitive information (kernel memory). (CVE-2020-12352)

 Andy Nguyen discovered that the Bluetooth HCI event packet parser in the Linux kernel did not properly handle event advertisements of certain sizes, leading to a heap-based buffer overflow. A physically proximate remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-24490)

 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;

 - Media drivers;

 - Network drivers;

 - SMB network file system;

 - Bluetooth subsystem;

 - Amateur Radio drivers;

 - Network traffic control;

 - VMware vSockets driver; (CVE-2024-43904, CVE-2024-35963, CVE-2024-35967, CVE-2024-40973, CVE-2024-26822, CVE-2024-35965, CVE-2024-40910, CVE-2024-38553, CVE-2024-53057, CVE-2024-50264, CVE-2024-35966)

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.
