Name of the Vulnerable Software and Affected Versions Cisco IOS on Aironet access points (affected versions not specified)

Description The issue is related to the DHCP implementation, which does not handle error conditions properly, specifically with short leases and unsuccessful lease-renewal attempts. This can be exploited by remote attackers to cause a denial of service, resulting in a device restart. The attack triggers a transition into a recovery state that was intended for a network-interface restart but instead causes a full device restart.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
