Summary
In the Linux kernel, the following vulnerability has been resolved: soc: samsung: exynos-pmu: fix use-after-free of interrupt generator node The setup_cpuhp_and_cpuidle() parses the device tree node for the interrupt generation block via of_parse_phandle() and decrements its reference count using of_node_put() immediately after fetching the resource address. However, later the intr_gen_node pointer is passed into of_syscon_register_regmap(). Fix this by declaring intr_gen_node with __free() and removing of_node_put().
