In the Linux kernel, the following vulnerability has been resolved:
net: sched: sch_multiq: fix possible OOB write in multiq_tune()
q->bands will be assigned to qopt->bands to execute subsequent code logic
after kmalloc. So the old q->bands should not be used in kmalloc.
Otherwise, an out-of-bounds write will occur.
