A vulnerability in the Linux kernel's CPU hotplug subsystem was resolved, where the states_show() function used sprintf() to write CPU hotplug state names into a sysfs buffer. This could cause a buffer overflow past the PAGE_SIZE limit when many states are registered. The issue was fixed by switching to sysfs_emit_at() to ensure bounded output.
