USN-1508-1: Linux kernel (OMAP4) vulnerability

Releases

• Ubuntu 12.04

Packages

• linux-ti-omap4 - Linux kernel for OMAP4

Details

An error was discovered in the Linux kernel's memory subsystem (hugetlb).
An unprivileged local user could exploit this flaw to cause a denial of
service (crash the system).

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 12.04

• linux-image-3.2.0-1416-omap4 - 3.2.0-1416.22

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. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
