Ubuntu Security Notice USN-6742-2
April 23, 2024<\/p>\n
linux-azure, linux-lowlatency, linux-nvidia vulnerabilities
==========================================================================<\/p>\n
A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
– Ubuntu 22.04 LTS<\/p>\n
Summary:<\/p>\n
Several security issues were fixed in the Linux kernel.<\/p>\n
Software Description:
– linux-azure: Linux kernel for Microsoft Azure Cloud systems
– linux-lowlatency: Linux low latency kernel
– linux-nvidia: Linux kernel for NVIDIA systems<\/p>\n
Details:<\/p>\n
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)<\/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:
– JFS file system;
– Netfilter;
(CVE-2024-26581, CVE-2023-52600, CVE-2023-52603)<\/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-5.15.0-105-lowlatency 5.15.0-105.115
linux-image-5.15.0-105-lowlatency-64k 5.15.0-105.115
linux-image-5.15.0-1053-nvidia 5.15.0-1053.54
linux-image-5.15.0-1053-nvidia-lowlatency 5.15.0-1053.54
linux-image-5.15.0-1061-azure 5.15.0-1061.70
linux-image-azure-lts-22.04 5.15.0.1061.59
linux-image-lowlatency 5.15.0.105.100
linux-image-lowlatency-64k 5.15.0.105.100
linux-image-nvidia 5.15.0.1053.53
linux-image-nvidia-lowlatency 5.15.0.1053.53<\/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
