CVE-2024-27375

Heap overwrite via unchecked NAN length

Published Jun 5, 2024 · Updated Feb 13, 2025

Heap overwrite in Samsung Exynos 980, 850, 1280, 1380, and 1330 allows local users with high privileges to corrupt memory. slsi_nan_followup_get_nl_params() uses the userspace-controlled hal_req->sdea_service_specific_info_len value without validating it before processing service-specific information. The malformed local request overwrites heap memory; Samsung does not document a specific post-corruption outcome beyond the resulting confidentiality, integrity, and service risks.
