CVE-2024-27378

Memory disclosure via unchecked userspace length

Published Jun 5, 2024 · Updated Mar 13, 2025

Improper input validation in Samsung Exynos mobile processors allows local users to read heap memory or interrupt service via userspace input. slsi_send_action_frame_cert() accepts a userspace-supplied len value without validating it before a heap read, allowing the read to cross the intended buffer boundary. High-privileged local access is required on Exynos 980, 850, 1280, 1380, or 1330; the precise interruption mode is unpublished.
