Use-After-Free in MongoDB Geospatial Validation Leads to Denial of Service

Assigner: mongodb
Reserved: 03.08.2026 Published: 11.08.2026 Updated: 11.08.2026

An issue in MongoDB Server's geospatial validation could allow an authenticated user with write privileges to cause an internal reference to be used after the underlying memory has been freed, through concurrent operations against a collection using a certain type of validator. This could result in a server crash, leading to a denial of service.
