CVE-2022-49719 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: irqchip/gic/realview: Fix refcount leak in realview_gic_of_init of_find_matching_node_and_match() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak.. EPSS estimates a 0.24% chance of exploitation in the next 30 days.
