Description

A flaw was found in the Linux kernel. This vulnerability, a use-after-free (UAF), occurs within the of_unittest_changeset() function due to improper handling of device node references. An attacker could exploit this by causing a device node's memory to be freed while it is still in use. This could lead to a system crash, resulting in a Denial of Service (DoS).
