CVE-2024-27380

Heap data disclosure via unchecked ioctl length

Published Jun 5, 2024 · Updated Mar 20, 2025

Out-of-bounds read in Samsung Mobile Processor Exynos 980, 850, 1280, 1380, and 1330 allows local users to read beyond a heap buffer. The slsi_set_delayed_wakeup_type() function uses an ioctl_args->args[i] length from userspace without validating it before accessing heap data. High privileges and local ioctl access are required; exploitation can disclose adjacent heap contents, while the availability failure mode is unpublished.
