What is CVE-2024-20433?

A vulnerability exists in the Resource Reservation Protocol (RSVP) feature of Cisco IOS Software and Cisco IOS XE Software. This issue is caused by a buffer overflow that occurs when the software processes specially crafted RSVP packets. An unauthenticated, remote attacker could exploit this vulnerability by sending malicious RSVP traffic to an affected device, potentially causing it to reload unexpectedly. The result of such an exploit would lead to a denial of service (DoS), affecting the availability of network services.
