CVE-2022-49457 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: ARM: versatile: Add missing of_node_put in dcscb_init The device_node pointer is returned by of_find_compatible_node with refcount incremented. We should use of_node_put() to avoid the refcount leak.. EPSS estimates a 0.25% chance of exploitation in the next 30 days.
