Releases
Packages
- linux-intel-iot-realtime - Linux kernel for Intel IoT Real-time platforms
- linux-realtime - Linux kernel for Real-time systems
Details
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:
- GPU drivers;
- SMB network file system;
- Network namespace;
- Networking core;
(CVE-2024-26928, CVE-2024-56658, CVE-2024-35864, CVE-2024-57798)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 22.04
-
linux-image-5.15.0-1074-intel-iot-realtime
-
5.15.0-1074.76
-
linux-image-5.15.0-1081-realtime
-
5.15.0-1081.89
-
linux-image-intel-iot-realtime
-
5.15.0.1074.78
-
linux-image-realtime
-
5.15.0.1081.84
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.
