An issue was discovered in Samsung Mobile Processor Exynos 980, Exynos 850, Exynos 1280, Exynos 1380, and Exynos 1330. In the function slsi_nan_followup_get_nl_params(), there is no input validation check on hal_req->service_specific_info_len coming from userspace, which can lead to a heap overwrite.
The product writes data past the end, or before the beginning, of the intended buffer.
The product receives a complex input with multiple elements or fields that must be consistent with each other, but it does not validate or incorrectly validates that the input is actually consistent.
