An issue was discovered in Samsung Mobile Processor Exynos 980, Exynos 850, Exynos 1280, Exynos 1380, and Exynos 1330. In the function slsi_nan_get_security_info_nl(), there is no input validation check on sec_info->key_info.body.pmk_info.pmk_len coming from userspace, which can lead to a heap overwrite.
