## Overview

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

block: mtip32xx: synchronize ioctls with device removal

The ioctl handlers only test REMOVE_PENDING before entering
mtip_hw_ioctl(). Removal can set that bit immediately afterwards and free
dd->port in mtip_hw_exit() while an ioctl still dereferences it. An already
open block device can reach the handlers while del_gendisk() is in
progress.

Serialize both native and compat ioctls with removal. Set REMOVE_PENDING
before taking the mutex so new callers fail after an in-flight ioctl has
drained, and hold the mutex until the port has been torn down.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
