A vulnerability was found in DPDK versions 18.11 and above. The vhost-crypto library code is missing validations for user-supplied values, potentially allowing an information leak through an out-of-bounds memory read.
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.
The product reads data past the end, or before the beginning, of the intended buffer.
