Updated under an hour ago ()

Does this affect you?

It affects MongoDB Inc MongoDB Server. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

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.
