CVE-2025-38719

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.

Summary		(es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: net: hibmcge: corrige el problema de división por cero Cuando el puerto de red está inactivo, la cola es liberada, y ring->len es 0. En debugfs, se llamará a hbg_get_queue_used_num(), lo que puede llevar a un problema de división por cero. Este parche añade una comprobación, si ring->len es 0, hbg_get_queue_used_num() devuelve directamente 0.
