Vulnerability from github – Published: 2024-07-11 00:32 – Updated: 2024-10-01 21:31An Improper Handling of Exceptional Conditions vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a logically adjacent downstream RSVP neighbor to cause kernel memory exhaustion, leading to a kernel crash, resulting in a Denial of Service (DoS).
The kernel memory leak and eventual crash will be seen when the downstream RSVP neighbor has a persistent error which will not be corrected.
System kernel memory can be monitored through the use of the 'show system statistics kernel memory' command as shown below:
