GHSA-R534-VWMW-5GMQ

Vulnerability from github – Published: 2025-09-05 18:31 – Updated: 2025-11-26 18:31

Details

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.

Severity ?

5.5 (Medium)
