(CVE-2023-52600, CVE-2024-26589, CVE-2024-26591, CVE-2024-26581,
CVE-2023-52603)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 22.04
-
linux-image-6.5.0-1019-azure
-
6.5.0-1019.20~22.04.1
-
linux-image-6.5.0-1019-azure-fde
-
6.5.0-1019.20~22.04.1
-
linux-image-azure
-
6.5.0.1019.20~22.04.1
-
linux-image-azure-fde
-
6.5.0.1019.20~22.04.1
After a standard system update you need to reboot your computer to make
all the necessary changes.
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.
