CVE-2025-21971

CVE-2025-21971 in the Linux kernel net_sched subsystem: creation of a Qdisc class with classid TC_H_ROOT (0xFFFFFFFF) could terminate traversal early during qdisc tree walk, causing incorrect root backlog statistics and potential CRASH in DRR. The fix prevents creating any Qdisc class with TC_H_R...

CVE-2024-53057 net/sched: stop qdisc_tree_reduce_backlog on TC_H_ROOT

In the Linux kernel, the following vulnerability has been resolved: net/sched: stop qdisctreereducebacklog on TCHROOT In qdisctreereducebacklog, Qdiscs with major handle ffff: are assumed to be either root or ingress. This assumption is bogus since it's valid to create egress qdiscs with major...

CVE-2024-53057

CVE-2024-53057 affects Linux kernel net/sched: qdisc_tree_reduce_backlog can UAF when major handle ffff: exists (egress qdiscs). Root cause: ffff: assumed to be root/ingress, fixed by stopping at TC_H_ROOT; the fix updates to avoid iterating into an ingress qdisc and halts when parent is TC_H_ROO...
