Vulnerability from variot
A vulnerability in the errdisable per VLAN feature of Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause the device to crash, leading to a denial of service (DoS) condition. The vulnerability is due to a race condition that occurs when the VLAN and port enter an errdisabled state, resulting in an incorrect state in the software. An attacker could exploit this vulnerability by sending frames that trigger the errdisable condition. A successful exploit could allow the attacker to cause the affected device to crash, leading to a DoS condition. The Cisco Catalyst 3650, 3850, and 4500E Series Switches are all different switches from Cisco. IOSXESoftware is a set of operating systems developed by Cisco for its network devices. A denial of service vulnerability exists in the errdisableperVLAN feature in IOSXESoftware in the Cisco Catalyst 3650, 3850, and 4500E Series Switches. Cisco IOS XE Software is prone to a denial-of-service vulnerability. This issue is being tracked by Cisco Bug ID CSCvh13611
