What it is

In the Linux kernel, the following vulnerability has been resolved:

net: rfkill: prevent unlimited numbers of rfkill events from being created

Userspace can create an unlimited number of rfkill events if the system

is so configured, while not consuming them from the rfkill file

descriptor, causing a potential out of memory situation. Prevent this

from bounding the number of pending rfkill events at a "large" number

(i.e. 1000) to prevent abuses like this.
