"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: rtw89: fix wrong pci_get_drvdata type in AER handlers\n\nrtw89 stores an ieee80211_hw pointer via pci_set_drvdata() at probe\ntime, but io_error_detected() and io_resume() retrieve it as a\nnet_device pointer. This causes netif_device_detach/attach to\noperate on an ieee80211_hw struct, reading and writing at wrong\noffsets. The adjacent io_slot_reset() already does it correctly.\n\nUse ieee80211_stop_queues/wake_queues instead, consistent with\nevery other queue stop/start path in the driver.\n\nTested on RTL8852CE by calling the handlers from a test module\nbefore and after the fix."
