No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

The inotify_read function in the Linux kernel 2.6.27 to 2.6.27.13, 2.6.28 to 2.6.28.2, and 2.6.29-rc3 allows local users to cause a denial of service (OOPS) via a read with an invalid address to an inotify instance, which causes the device's event list mutex to be unlocked twice and prevents proper synchronization of a data structure for the inotify instance.
