Description

In the Linux kernel, the following vulnerability has been resolved: cpu: hotplug: Bound hotplug states sysfs output states_show() adds CPU hotplug state names into a single sysfs buffer using sprintf(). With enough registered states, this can write past the end of the PAGE_SIZE buffer. Use sysfs_emit_at() so output is bounded.
