Doc Text:
A flaw was found in valkey. An integer underflow in the `setDeferredReply` function of `networking.c` allows an adjacent network attacker to potentially trigger unexpected behavior. This underflow occurs when calculating `prev->size - prev->used`, leading to a condition that may result in a denial of service. The vulnerability is triggered by processing a specially crafted network packet.
