Technical details
The vulnerability exists in DCP Set and Identify request processing, where the implementation fails to verify that a complete block header is present in the receive buffer before reading the next block, leading to out-of-bounds reads. Additionally, DCP Set blocks with a length smaller than two bytes cause integer underflow, resulting in processing with an inflated 65534-byte length. An adjacent network attacker can trigger denial of service or memory disclosure.
