⚡ Technical Analysis
The root cause is a classic buffer overflow in a system service that processes incoming network packets.
The vulnerable component fails to properly validate the size of an incoming packet's payload before copying it into a fixed-size buffer in the system's memory.
An attacker can send a packet with a payload larger than the buffer's capacity, overflowing it and overwriting adjacent memory.
This memory corruption can be leveraged to divert the system's execution flow and run arbitrary code with elevated privileges.
