Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS : Linux kernel vulnerabilities (USN-6740-1)

high Nessus Plugin ID 193593

Language:

Synopsis

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

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6740-1 advisory.

 Wei Chen discovered that a race condition existed in the TIPC protocol implementation in the Linux kernel, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-1382)

 It was discovered that the virtio network implementation in the Linux kernel did not properly handle file references in the host, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information (kernel memory).
 (CVE-2023-1838)

 Jose Oliveira and Rodrigo Branco discovered that the Spectre Variant 2 mitigations with prctl syscall were insufficient in some situations. A local attacker could possibly use this to expose sensitive information.
 (CVE-2023-1998)

 Daniele Antonioli discovered that the Secure Simple Pairing and Secure Connections pairing in the Bluetooth protocol could allow an unauthenticated user to complete authentication without pairing credentials. A physically proximate attacker placed between two Bluetooth devices could use this to subsequently impersonate one of the paired devices. (CVE-2023-24023)

 shanzhulig discovered that the DRM subsystem in the Linux kernel contained a race condition when performing certain operation while handling driver unload, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-51043)

 It was discovered that a race condition existed in the Bluetooth subsystem of the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-51779)

 It was discovered that the device mapper driver in the Linux kernel did not properly validate target size during certain memory allocations. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-52429, CVE-2024-23851)

 Zhenghan Wang discovered that the generic ID allocator implementation in the Linux kernel did not properly check for null bitmap when releasing IDs. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-6915)

 It was discovered that the SCTP protocol implementation in the Linux kernel contained a race condition when handling lock acquisition in certain situations. A local attacker could possibly use this to cause a denial of service (kernel deadlock). (CVE-2024-0639)

 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:

 - Architecture specifics;

 - EDAC drivers;

 - Media drivers;

 - JFS file system; (CVE-2023-52603, CVE-2023-52464, CVE-2023-52600, CVE-2023-52445, CVE-2023-52451)

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.
