USN-7122-1: Linux kernel vulnerability
19 November 2024
The system could be made to crash under certain conditions.
Releases
Packages
- linux - Linux kernel
Details
A security issue was discovered in the Linux kernel.
An attacker could possibly use this to compromise the system.
This update corrects flaws in the following subsystems:
- x86 architecture;
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.04
-
linux-image-3.13.0-200-generic
-
3.13.0-200.251
Available with Ubuntu Pro
-
linux-image-3.13.0-200-lowlatency
-
3.13.0-200.251
Available with Ubuntu Pro
-
linux-image-generic
-
3.13.0.200.210
Available with Ubuntu Pro
-
linux-image-generic-lts-trusty
-
3.13.0.200.210
Available with Ubuntu Pro
-
linux-image-lowlatency
-
3.13.0.200.210
Available with Ubuntu Pro
-
linux-image-server
-
3.13.0.200.210
Available with Ubuntu Pro
-
linux-image-virtual
-
3.13.0.200.210
Available with Ubuntu Pro
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.
