[SRU][L/K/J/F][PATCH 0/1] CVE-2022-31436

[Yuxuan Luo]

[Impact]
When the MTU of the loopback device feeds a large number, net/sched/sch_qfq.c
allows a out-of-bounds read/write error, detriment system's integrity.

[Backport]
It is a clean cherry pick for all affected releases.

[Test]
Compile and smoke tested via modprobe and rmmod the sch_fq module.

[Potential Regression]
Expecting little regression potential since the patch only adds an additional
layer of checking without manipulating the memory.
