- Summary
- wifi: rtw88: fix wrong pci_get_drvdata type in AER handlers
- Details
-
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.
