CVE-2025-21971 net_sched: Prevent creation of classes with TC_H_ROOT

In the Linux kernel, the following vulnerability has been resolved: netsched: Prevent creation of classes with TCHROOT The function qdisctreereducebacklog uses TCHROOT as a termination condition when traversing up the qdisc tree to update parent backlog counters. However, if a class is created wi...

CVE-2025-21971

Summary (CVE-2025-21971): In the Linux kernel, an issue in net_sched can cause incorrect parent backlog statistics when a Qdisc class is created with classid TC_H_ROOT (0xFFFFFFFF). The traversal in qdisc_tree_reduce_backlog() terminates at TC_H_ROOT instead of the actual root, which can lead to ...
