CVE-2024-53164

CVE-2024-53164 affects the Linux kernel net_sched subsystem. The root cause was an incorrect ordering of qlen updates (sch->q.qlen) around qdisc_tree_reduce_backlog(), which could fail to notify parent qdiscs when a child becomes empty. The fix ensures the qlen adjustment happens before the ca...
