    Cisco IOS, XR, and XE Software Buffer Overflow Vulnerability — 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. Listed in the CISA KEV catalog (added 2022-03-03) — confirmed exploited in the wild, not theoretical. FIRST EPSS puts the chance of exploitation in the next 30 days at ~3%. Treat it as real and prioritize remediation over triage.
