Vulnerability Title
wifi: rtw88: fix wrong pci_get_drvdata type in AER handlers
Source: CVE Program / CVE List V5
Vulnerability Description
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.

Vulnerability Description
Linux kernel是美国Linux基金会开源的一个操作系统内核。 Linux kernel 6.17版本存在安全漏洞，该漏洞源于rtw88驱动在AER处理程序中错误地将pci_get_drvdata返回的ieee80211_hw指针当作net_device指针使用，导致netif_device_detach/attach在错误的偏移上读写操作。
