CVE-2024-43830 is a use-after-free race in the Linux kernel LED trigger subsystem. LED triggers with trigger-specific sysfs attributes commonly allocate per-trigger data during their activate() callback and free it during deactivate(). The vulnerable deactivation ordering invoked deactivate() before removing the trigger's sysfs attribute groups. Consequently, concurrent sysfs show or store callbacks could run after deactivation and access trigger data that had already been freed. The fix removes the sysfs attribute groups before calling deactivate(), reversing activation order and preventing post-deactivation sysfs access to freed trigger data.
