The internal locking mechanism of the MongoDB server uses an internal encoding of the resources in order to choose what lock to take. Collections may inadvertently collide with one another in this representation causing unavailability between them due to conflicting locks.

MongoDB server's resource locking mechanism can cause unintended collisions between collections due to improper internal encoding, leading to service denial of availability. Authenticated users can trigger this condition to disrupt database operations across affected collections without requiring user interaction. No patch is currently available to remediate this vulnerability.
