CVE-2026-98333

Estado: RecibidaSin puntuar—

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:

Undo the LED state in the error path.
