This vulnerability is due to insufficient access controls to a shared memory resource. An attacker could exploit this vulnerability by corrupting a shared memory segment on an affected device. A successful exploit could allow the attacker to cause the device to reload. The device will recover from the corruption upon reboot. After additional investigation it was determined that this vulnerability is not exploitable in production software. Cisco has provided software updates for this issue.
