CVE-2026-31670

Опубликовано: 24 апр. 2026

CVSS3: 5.5

Описание

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.

A flaw was found in the Linux kernel's rfkill component. A local user can exploit this by creating an excessive number of rfkill events without properly consuming them. This can lead to a denial of service (DoS) due to an out-of-memory condition, impacting system stability and availability.
