Technical description

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

wifi: mac80211: reset the LED state when ifup fails

When the first interface comes up, the radio LED is turned on. This can

start the TPT trigger timer, which continues running.

But if bringing up the interface fails then the timer keeps running and

won't be stopped by anything, eventually it can be freed:

ODEBUG: free active (active state 0) object: ffff888127e12130 object type: timer_list hint: tpt_trig_timer+0x0/0x300 net/mac80211/led.c:145
