CWE ids for CVE-2021-40401
-
The product does not check the return value from a method or function, which can prevent it from detecting unexpected states and conditions.Assigned by:
- nvd@nist.gov (Primary)
- talos-cna@cisco.com (Secondary)
-
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.Assigned by: nvd@nist.gov (Secondary)
