CVE-2025-52516

Denial of service via invalid kernel address dereference

Published Jan 5, 2026 · Updated Jan 5, 2026

Denial of service in the issimian camera driver for Samsung Exynos 1330, 1380, 1480, 1580, 2400, and 2500 allows local users to crash devices. The driver dereferences an invalid kernel address during camera processing, faulting the kernel instead of rejecting the address. Exploitation requires local access but no privileges or user interaction, and the reported impact is limited to availability.
