There is an IT security warning for Linux Kernel. Here you can find out which vulnerabilities are involved, which products are affected and what you can do.
The Federal Office for Security in der Informationstechnik (BSI) published an update on July 14, 2023 to a security hole for Linux Kernel that became known on May 12, 2022. The Linux and NetApp Appliance operating systems and the products Open Source Linux Kernel, Debian Linux, Amazon Linux 2, Red Hat Enterprise Linux, Ubuntu Linux, SUSE Linux, Oracle Linux and NetApp FAS are affected by the vulnerability.
The latest manufacturer recommendations regarding updates, workarounds and security patches for this vulnerability can be found here: Amazon Linux Security Advisory ALASKERNEL-5.15-2023-023 (Status: 07/13/2023). Other useful links are listed later in this article.
Security Advice for Linux Kernel – Risk: medium
Risk level: 3 (medium)
CVSS Base Score: 5,3
CVSS Temporal Score: 4,6
Remote Attack: No
The Common Vulnerability Scoring System (CVSS) is used to assess the severity of vulnerabilities in computer systems. The CVSS standard makes it possible to compare potential or actual security vulnerabilities based on various criteria in order to create a list of priorities for initiating countermeasures. The attributes “none”, “low”, “medium”, “high” and “critical” are used for the severity of a vulnerability. The base score assesses the prerequisites for an attack (including authentication, complexity, privileges, user interaction) and its consequences. With the temporal score, framework conditions that change over time are included in the evaluation. The severity of the vulnerability discussed here is classified as “medium” according to the CVSS with a base score of 5.3.
Linux Kernel Bug: Vulnerability allows security measures to be circumvented
The kernel represents the core of the Linux operating system.
A local attacker can exploit a vulnerability in the Linux kernel to bypass security measures.
The vulnerability was classified by the individual serial number using the CVE reference system (Common Vulnerabilities and Exposures). CVE-2022-30594.

General measures for dealing with IT security gaps
Users of the affected systems should keep them up to date. When security gaps become known, manufacturers are required to remedy them as quickly as possible by developing a patch or a workaround. If new security updates become available, install them as soon as possible. For information purposes, consult the sources listed in the next section. These often contain further information on the latest version of the software in question and the availability of security patches or tips on workarounds. If you have any further questions or are unsure, contact your responsible administrator. IT security officers should regularly check the sources mentioned to see whether a new security update is available.
