CVE-2025-38719

Summary

In the Linux kernel, the following vulnerability has been resolved:

net: hibmcge: fix the division by zero issue

When the network port is down, the queue is released, and ring->len is 0. In debugfs, hbg_get_queue_used_num() will be called, which may lead to a division by zero issue.

This patch adds a check, if ring->len is 0, hbg_get_queue_used_num() directly returns 0.
