Summary
The SIP module in certain Huawei products is exposed to a denial of service vulnerability, enabling remote attackers to exploit it by sending specially crafted messages. Insufficient verification of incoming packets can lead to buffer overflow conditions, resulting in a dead loop and a denied service state on the affected device. This poses significant risks to network availability and integrity, making security patches essential to mitigate these risks.
