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...

CVE-2021-47512 net/sched: fq_pie: prevent dismantle issue

In the Linux kernel, the following vulnerability has been resolved: net/sched: fqpie: prevent dismantle issue For some reason, fqpiedestroy did not copy working code from piedestroy and other qdiscs, thus causing elusive bug. Before calling deltimersync&q-adapttimer, we need to ensure timer will...
