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.
