kernel: net/sched: Always pass notifications when child class becomes empty

A use-after-free UAF vulnerability was found in the Linux kernel's net/sched subsystem, specifically in the Credit-Based Shaper CBS qdisc implementation schcbs. The vulnerability occurs because the CBS qdisc's reset function qdiscresetqueue only resets its internal queue but fails to reset its...

SUSE 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, hbggetqueueusednum will be called, which may lead to a division by zero issue. This patch adds a...

CVE-2025-38719

The CVE-2025-38719 entry concerns the Linux kernelnet hibmcge: when the network port is down, a released queue can yield ring->len = 0, triggering a division by zero in hbg_get_queue_used_num() called from debugfs. The provided patch adds a guard: if ring->len is 0, hbg_get_queue_used_num()...
