In the Linux kernel, the following vulnerability has been resolved:

wifi: rtlwifi: rtl8192du: Fix possible memory leak in rtl92du_init_sw_vars()

The memory allocated inside rtl92du_init_shared_data() is not freed in
any of the subsequent error paths in rtl92du_init_sw_vars().
Fix that by adding a call to rtl92du_deinit_shared_data() in the error
path.
