Vulnerability

Field	Value
ID	V-001
Severity	CRITICAL
Scanner	multi_agent_ai
Rule	V-001
File	modxo/modxo_queue.c:49

Description: The queue implementation performs two memcpy operations using queue->item_size as the copy length without validating that item_size is within the bounds of the destination buffer. If queue->item_size is corrupted or set to a value larger than the allocated queue slot, the memcpy at line 49 (enqueue) and line 61 (dequeue) will overflow the destination buffer, corrupting adjacent heap or stack memory on the embedded target.

Changes
