CVE-2026-69025: Samsung Exynos NPU driver out-of-bounds write in ioctl handler

CVE-2026-69025 · Severity: info · Published 2026-11-05

The Exynos NPU driver, which manages neural processing capabilities in Samsung processors, contains a flaw in its input validation that allows local attackers to write data outside intended memory boundaries. This out-of-bounds write can crash the system, causing denial of service.

Vendors: Samsung.

Technical details

The vulnerability exists in the ioctl handler of the Exynos NPU driver, where improper validation of user-supplied input allows an out-of-bounds write. The attack requires local code execution (ioctl calls from user space), and successful exploitation results in denial of service through memory corruption.
