Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A vulnerability in the Linux kernel has been resolved. The issue concerned the codel (controlled delay) qdisc (queueing discipline) in the kernel. Specifically, the problem involved the
qlen check before qdisc tree reduce backlog() and the qlen!=0 checks in fq codel dequeue() and codel qdisc dequeue(). These checks have been removed after making all ->qlen notify() callbacks idempotent, ensuring it is safe to do so.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
