Ubuntu Security Notice USN-6775-2
May 21, 2024<\/p>\n
linux-aws, linux-aws-5.15, linux-gke vulnerabilities
==========================================================================<\/p>\n
A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
– Ubuntu 22.04 LTS
– Ubuntu 20.04 LTS<\/p>\n
Summary:<\/p>\n
Several security issues were fixed in the Linux kernel.<\/p>\n
Software Description:
– linux-aws: Linux kernel for Amazon Web Services (AWS) systems
– linux-gke: Linux kernel for Google Container Engine (GKE) systems
– linux-aws-5.15: Linux kernel for Amazon Web Services (AWS) systems<\/p>\n
Details:<\/p>\n
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)<\/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:
– MAC80211 subsystem;
– Tomoyo security module;
(CVE-2024-26622, CVE-2023-52530)<\/p>\n
Update instructions:<\/p>\n
The problem can be corrected by updating your system to the following
package versions:<\/p>\n
Ubuntu 22.04 LTS
linux-image-5.15.0-1059-gke 5.15.0-1059.64
linux-image-5.15.0-1062-aws 5.15.0-1062.68
linux-image-aws-lts-22.04 5.15.0.1062.62
linux-image-gke 5.15.0.1059.58
linux-image-gke-5.15 5.15.0.1059.58<\/p>\n
Ubuntu 20.04 LTS
linux-image-5.15.0-1062-aws 5.15.0-1062.68~20.04.1
linux-image-aws 5.15.0.1062.68~20.04.1<\/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
