linux-aws-5.4 vulnerabilities
==========================================================================<\/p>\n
A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
– Ubuntu 18.04 LTS<\/p>\n
Summary:<\/p>\n
Several security issues were fixed in the Linux kernel.<\/p>\n
Software Description:
– linux-aws-5.4: Linux kernel for Amazon Web Services (AWS) systems<\/p>\n
Details:<\/p>\n
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)<\/p>\n
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:
– Netfilter;
(CVE-2024-26925, CVE-2024-26643)<\/p>\n
Update instructions:<\/p>\n
The problem can be corrected by updating your system to the following
package versions:<\/p>\n
Ubuntu 18.04 LTS
linux-image-5.4.0-1127-aws 5.4.0-1127.137~18.04.2
Available with Ubuntu Pro
linux-image-aws 5.4.0.1127.137~18.04.1
Available with Ubuntu Pro<\/p>\n
After a standard system update you need to reboot your computer to make
all the necessary changes.<\/p>\n
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.<\/p>\n
