CWE ids for CVE-2022-0523

  • The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
    Assigned by: nvd@nist.gov (Primary)
  • 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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

    • nvd@nist.gov (Secondary)
    • security@huntr.dev (Primary)
  • The product dereferences a pointer that contains a location for memory that was previously valid, but is no longer valid.
