CVE-2024-27382

Heap-data disclosure via unchecked userspace length

Published Jun 5, 2024 · Updated Mar 18, 2025

Out-of-bounds read in Samsung Exynos mobile processors allows local users to disclose heap data through a crafted userspace length. The slsi_send_action_frame() function trusts the userspace-supplied len value without validating it before reading from a heap buffer. Successful access requires high local privileges, and the resulting over-read discloses adjacent heap contents or interrupts the affected component.
