## Overview

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

wifi: rtw88: fix wrong pci_get_drvdata type in AER handlers

rtw88 stores an ieee80211_hw pointer via pci_set_drvdata() at probe
time, but io_error_detected() and io_resume() retrieve it as a
net_device pointer.  This causes netif_device_detach/attach to
operate on an ieee80211_hw struct, reading and writing at wrong
offsets.

Use ieee80211_stop_queues/wake_queues instead, consistent with
every other queue stop/start path in the driver.

## Remediation

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