## Overview

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.

## Affected

- `linux_kernel >= 5.4, < 5.4.279`
- `linux_kernel >= 5.5, < 5.10.221`
- `linux_kernel >= 5.11, < 5.15.162`
- `linux_kernel >= 5.16, < 6.1.95`
- `linux_kernel >= 6.2, < 6.6.35`
- `linux_kernel >= 6.7, < 6.9.6`
- `linux_kernel = 6.10`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.9.6`
