Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: wifi: wilc1000: fix RCU usage in connect path With lockdep enabled, calls to the connect function from cfg802.11 layer lead to the following warning: ============================= WARNING: suspicious RCU usage 6.7.0-rc1-wt+ #333 Not tainted ----------------------------- drivers/net/wireless/microchip/wilc1000/hif.c:386 suspicious rcu_dereference_check() usage!

Fix RCU dereference usage by moving it to a RCU read critical section. To avoid wrapping the whole wilc_parse_join_bss_param under the critical section, just use the critical section to copy ies data
