Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: rfkill: prevent unlimited numbers of rfkill events from being created<br /> <br /> Userspace can create an unlimited number of rfkill events if the system<br /> is so configured, while not consuming them from the rfkill file<br /> descriptor, causing a potential out of memory situation. Prevent this<br /> from bounding the number of pending rfkill events at a "large" number<br /> (i.e. 1000) to prevent abuses like this.
