CVE-2021-47557

Summary (CVE-2021-47557) : In the Linux kernel, the net/sched sch_ets code could expose a NULL pointer dereference in the DRR active list when the number of DRR classes decreases, allowing a crash via cl->qdisc->ops->peek(cl->qdisc) if cl->qdisc is NULL. This affects the ETS qdisc ...

CVE-2021-47512

The CVE-2021-47512 issue affects the Linux kernel’s net/sched fq_pie/Qdisc handling. fq_pie_destroy() failed to copy logic from pie_destroy() and related qdiscs, risking a timer rearm during del_timer_sync(&q->adapt_timer) and potentially triggering an rcu stall or related instability. The pro...
