Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: mac80211: don&amp;#39;t flush non-uploaded STAs<br /> <br /> If STA state is pre-moved to AUTHORIZED (such as in IBSS<br /> scenarios) and insertion fails, the station is freed.<br /> In this case, the driver never knew about the station,<br /> so trying to flush it is unexpected and may crash.<br /> <br /> Check if the sta was uploaded to the driver before and<br /> fix this.
