Details

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

wifi: iwlegacy: fix broadcast stations deallocation

On the error path of __il4965_up(), il_dealloc_bcast_stations() clears only IL_STA_UCODE_ACTIVE, leaving IL_STA_BCAST set. This causes the same broadcast stations to be deallocated again by __il4965_down().

This can occur when RF_KILL is toggled during driver startup.

To fix clear the entire 'used' field, since we will not do any other operations on the station.
