The issue outlined in Ubuntu's USN-1499-1 pertains to a significant vulnerability in the linux-ti-omap4 kernel that can lead to system instability triggered by specific network packets.
The system could be made to crash if it received specially crafted network traffic.

Summary

The system could be made to crash if it received specially crafted network

traffic.

Software Description:

- linux-ti-omap4: Linux kernel for OMAP4

Details:

A flaw was discovered in the Linux kernel's NFSv4 (Network file system)

handling of ACLs (access control lists). A remote NFS server (attacker)

could cause a denial of service (OOPS).

Update Instructions

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

Ubuntu 11.10:
  linux-image-3.0.0-1212-omap4    3.0.0-1212.24

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.
