May 11, 2018
- Cisco Carrier Routing System
Known Affected Releases
Symptom: mpls_ldp may crash when unconfiguring MPLS LDP feature. Conditions: When MPLS LDP feature is unconfigured and the mpls_ldp process is cleaning up its resources, one of the task is to unregister from RIB for receiving prefix notifications. However, mpls_ldp does not check whether or not it has registered with RIB on this notification prior to calling the unregister. When unregister is called when mpls_ldp has not registered to RIB, crash occurs due to deferencing a NULL pointer.
