Local memory disclosure via unchecked userspace length
Published Jun 5, 2024 · Updated Mar 13, 2025
Heap over-read in Samsung Mobile Processor Exynos 980, 850, 1280, 1380, and 1330 allows local users to read adjacent heap memory. slsi_send_action_frame_ut() accepts a userspace-supplied len value without checking it against the backing heap buffer before reading. High-privilege local access is required, and successful exploitation exposes memory without enabling data modification.
