Releases
Packages
- linux-lts-trusty - Linux hardware enablement kernel from Trusty
Details
It was discovered that the Linux kernel's Infiniband subsystem did not
properly sanitize its input parameters while registering memory regions
from userspace. A local user could exploit this flaw to cause a denial of
service (system crash) or to potentially gain administrative privileges.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04
-
linux-image-3.13.0-46-generic-lpae
-
3.13.0-46.79~precise1
-
linux-image-3.13.0-46-generic
-
3.13.0-46.79~precise1
After a standard system update you need to reboot your computer to make
all the necessary changes.
