Description
A vulnerability in the Linux kernel's iwlegacy wifi driver causes improper deallocation of broadcast stations during error handling in driver startup, specifically when RF_KILL is toggled. The issue arises because only part of the station state is cleared, leading to double deallocation. This flaw has been fixed by clearing the entire 'used' field to prevent repeated deallocation.
