Search: CVE-2026-64012

A vulnerability in the Linux kernel's network scheduler (net/sched) subsystem, specifically in the sch_sfb queuing discipline, could cause a kernel panic when sfb has child qdiscs such as qfq. The issue arises from a direct dequeue call instead of using the appropriate peek and dequeue method, leading to a null pointer dereference. This flaw has been fixed by replacing the direct dequeue call with the qdisc_dequeue_peeked() method to properly handle skb retrieval from child qdiscs.
