Summary
net/sched: taprio: always validate TCA_TAPRIO_ATTR_PRIOMAP
Details

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

net/sched: taprio: always validate TCATAPRIOATTR_PRIOMAP

If one TCATAPRIOATTRPRIOMAP attribute has been provided, taprioparsemqprioopt() must validate it, or userspace can inject arbitrary data to the kernel, the second time taprio_change() is called.

First call (with valid attributes) sets dev->num_tc to a non zero value.

Second call (with arbitrary mqprio attributes) returns early from taprioparsemqprio_opt() and bad things can happen.
