FKIE_CVE-2026-23791

Vulnerability from fkie_nvd - Published: 2026-09-14 02:17 - Updated: 2026-09-14 02:17
Severity
4.2 (Medium) - CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:N/I:L/A:L
Summary
An issue was discovered in DPU in Samsung Mobile Processor Exynos 1280, 2200, 1380, 1480, 2400, 1580, 2500, 1680, and 2600. An out-of-bounds write vulnerability in the Exynos DPU driver (due to missing input length validation in color mode LUT parsing) leads to kernel memory corruption and potential privilege escalation.
