A malformed OMACP WAP push message can cause memory corruption on a Samsung S7 Edge device when processing the String Extension portion of the WbXml payload. This is due to an integer overflow in memory allocation for this string. The Samsung ID is SVE-2018-11463.
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.
