Subject: RE: [EXT] [PATCH] mwifiex: Fix memory corruption in dump_station

Hi Pali,

> The mwifiex_cfg80211_dump_station() uses static variable for iterating over
> a linked list of all associated stations (when the driver is in UAP role). This has
> a race condition if .dump_station is called in parallel for multiple interfaces.
> This corruption can be triggered by registering multiple SSIDs and calling, in
> parallel for multiple interfaces
>     iw dev <iface> station dump

Thanks for this change.
