CWE ids for CVE-2019-11810

CWE-416 Use After Free

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 (Primary)
CWE-476 NULL Pointer Dereference

The product dereferences a pointer that it expects to be valid but is NULL.

Assigned by: nvd@nist.gov (Primary)
