CVE-2024-46800: sch/netem: fix use after free in netem_dequeue

Published Sep 18, 2024
·
Updated

In the Linux kernel, the following vulnerability has been resolved:

sch/netem: fix use after free in netemdequeue

If netemdequeue() enqueues packet to inner qdisc and that qdisc returns NETXMITSTOLEN. The packet is dropped but qdisctreereducebacklog() is not called to update the parent's q.qlen, leading to the similar use-after-free as Commit e04991a48dbaf382 ("netem: fix return value if duplicate enqueue fails")

Commands to trigger KASAN UaF:

ip link add type dummy ip link set lo up ip link set dummy0 up tc qdisc add dev lo parent root handle 1: drr tc filter add dev lo parent 1: basic classid 1:1 tc class add dev lo classid 1:1 drr tc qdisc add dev lo parent 1:1 handle 2: netem tc qdisc add dev lo parent 2: handle 3: drr tc filter add dev lo parent 3: basic classid 3:1 action mirred egress redirect dev dummy0 tc class add dev lo classid 3:1 drr ping -c1 -W0.01 localhost # Trigger bug tc class del dev lo classid 1:1 tc class add dev lo classid 1:1 drr ping -c1 -W0.01 localhost # UaF
