A use-after-free was found in the way the sch_sfb enqueue function used the socket buffer (SKB) cb field after the same SKB had been enqueued (and freed) into a child qdisc. This flaw allows a local, unprivileged user to crash the system, causing a denial of service.</p> <p><strong>Affected:</strong> Linux Kernel</p> <p>A flaw was found in the Linux kernel’s networking code.
