Related CWEs
CWE-125
Out-of-bounds Read
The product reads data past the end, or before the beginning, of the intended buffer.
CWE-190
Integer Overflow or Wraparound
The product performs a calculation that can
produce an integer overflow or wraparound when the logic
assumes that the resulting value will always be larger than
the original value. This occurs when an integer value is
incremented to a value that is too large to store in the
associated representation. When this occurs, the value may
become a very small or negative number.
CWE-822
Untrusted Pointer Dereference
The product obtains a value from an untrusted source, converts this value to a pointer, and dereferences the resulting pointer.
