CVE-2024-27373

Local heap overwrite via unchecked mesh ID length

Published Jun 5, 2024 · Updated Mar 25, 2025

Out-of-bounds write in Samsung Exynos 980, 850, 1280, 1380, and 1330 processors allows local users to overwrite heap memory. The slsi_nan_config_get_nl_params() function uses the userspace-supplied disc_attr->mesh_id_len without validating it against the destination buffer. Reaching the path requires local high-privileged access; successful exploitation can compromise confidentiality, integrity, and availability.
