CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's rtw89 driver, where an incorrect data type is used in AER handlers, leading to improper handling of the ieee80211_hw pointer as a net_device pointer. This mismanagement can result in erroneous operations on network device structures, potentially causing system instability or crashes. Organizations utilizing affected Linux systems, particularly those relying on the RTL8852CE chipset, should prioritize applying the fix to ensure network reliability and security.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: wifi: rtw89: fix wrong pci_get_drvdata type in AER handlers rtw89 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. The adjacent io_slot_reset() already does it correctly. Use ieee80211_stop_queues/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.
