- wifi: rtw89: fix wrong pci_get_drvdata type in AER handlers
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: fix wrong pcigetdrvdata type in AER handlers
rtw89 stores an ieee80211hw pointer via pcisetdrvdata() at probe time, but ioerrordetected() and ioresume() retrieve it as a netdevice pointer. This causes netifdevicedetach/attach to operate on an ieee80211hw struct, reading and writing at wrong offsets. The adjacent ioslotreset() already does it correctly.
Use ieee80211stopqueues/wake_queues instead, consistent with every other queue stop/start path in the driver.
Tested on RTL8852CE by calling the handlers from a test module before and after the fix.
