Vulnerability Title
net: Stack Overflow with Ping (to own IP Address) via Shell
Source: NVD (National Vulnerability Database)
Vulnerability Description
Issuing an ICMP ping via the `net ping` shell command to a device's own IPv4 address causes the network stack to recursively re-enter the input path on the same system work-queue stack. Because the destination is recognized as a local address, both the echo request and the resulting echo reply are processed inline before the current frame returns. The nested input-path frames exceed the work-queue stack and trigger a stack overflow.

Vulnerability Title
Zephyr 安全漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Zephyr是Zephyr开源的一个可扩展的实时操作系统 (RTOS)。 Zephyr存在安全漏洞，该漏洞源于通过net ping shell命令向设备自身的IPv4地址发出ICMP ping时，网络堆栈递归地重新进入同一系统工作队列堆栈上的输入路径，导致嵌套输入路径帧超出工作队列堆栈并触发堆栈溢出。
