Weakness

CWE-591: Sensitive Data Storage in Improperly Locked Memory

The product stores sensitive data in memory that is not locked, or that has been incorrectly locked, which might cause the memory to be written to swap files on disk by the virtual memory manager. This can make the data more accessible to external actors.

How to prevent it
  • Architecture and Design: Identify data that needs to be protected from swapping and choose platform-appropriate protection mechanisms.
  • Implementation: Check return values to ensure locking operations are successful.
