Micrium OS Versions 5.10.1 and prior are vulnerable to integer wrap-around in functions Mem_DynPoolCreate, Mem_DynPoolCreateHW and Mem_PoolCreate. This unverified memory assignment can lead to arbitrary memory allocation, resulting in unexpected behavior such as very small blocks of memory being allocated instead of very large ones.

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.
