Availability,Integrity,Confidentiality
Technical Impact: Read Memory; Modify Memory; Execute Unauthorized Code or Commands; DoS: Crash, Exit, or Restart
If the returned stack buffer address is dereferenced after the return, then an attacker may be able to modify or read memory, depending on how the address is used. If the address is used for reading, then the address itself may be exposed, or the contents that the address points to. If the address is used for writing, this can lead to a crash and possibly code execution.
