Description
A vulnerability in the Linux kernel's mac80211 wireless subsystem caused the radio LED state and associated timer to remain active if bringing up the first wireless interface failed. This could lead to a timer being freed improperly, potentially causing kernel warnings or instability. The issue has been fixed by resetting the LED state on failure during interface initialization.
