CVE-2026-31670
Description
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.
