Ubuntu 22.04 LTS / 23.10 : Linux kernel vulnerabilities (USN-6774-1)

medium Nessus Plugin ID 197216

Language:

Synopsis

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

Description

The remote Ubuntu 22.04 LTS / 23.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6774-1 advisory.

 Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service (system crash). (CVE-2023-47233)

 Sander Wiebing, Alvise de Faveri Tron, Herbert Bos, and Cristiano Giuffrida discovered that the Linux kernel mitigations for the initial Branch History Injection vulnerability (CVE-2022-0001) were insufficient for Intel processors. A local attacker could potentially use this to expose sensitive information. (CVE-2024-2201)

 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:

 - Hardware random number generator core;

 - Ext4 file system;

 - JFS file system;

 - Bluetooth subsystem;

 - Networking core;

 - IPv4 networking;

 - Logical Link layer;

 - Netlink;

 - Tomoyo security module; (CVE-2024-26704, CVE-2023-52615, CVE-2024-26805, CVE-2023-52604, CVE-2024-26614, CVE-2023-52602, CVE-2024-26635, CVE-2024-26622, CVE-2023-52601, CVE-2024-26801)

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.
