Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
MongoDB 服务器文档值层中的竞态条件（race condition）可能导致并发的服务器线程在没有同步机制的情况下对同一块内部内存进行操作，从而引发内存损坏。拥有数据库普通读写权限的认证用户可能通过常规客户端协议触发该条件，导致服务器终止，并可能引发进程内存的损坏，且损坏的内容可能受用户输入的影响。成功利用该问题可能影响受影响服务器进程的机密性、完整性和可用性。

Vulnerability Title
Race Condition in MongoDB Server Document Value Layer Leads to Memory Corruption
Source: CVE Program / CVE List V5
Vulnerability Description
A race condition in the document value layer of MongoDB Server can allow concurrent server threads to operate on the same internal memory without synchronization, leading to memory corruption. An authenticated user holding ordinary read-write privileges on a database may be able to trigger this condition over the normal client protocol, resulting in server termination and potential corruption of process memory with user-influenced content. Successful use of this issue may impact the confidentiality, integrity, and availability of the affected server process.
