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. (NVD)
