EPSS Score3.5%

EPSS (Exploit Prediction Scoring System) estimates a 3.5% chance this CVE is exploited in the wild within the next 30 days — higher than 89% of all CVEs. It complements CVSS: a high EPSS on a mid-severity CVE can still be urgent.

Format string vulnerability in the Link Layer Discovery Protocol (LLDP) subsystem of Cisco IOS Software, Cisco IOS XE Software, and Cisco IOS XR Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition or execute arbitrary code with elevated privileges on an affected device.
