A component of the HarmonyOS has a Integer Overflow or Wraparound vulnerability. Local attackers may exploit this vulnerability to cause memory overwriting.
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.
