Privilege escalation via unchecked color-mode LUT length
Published Sep 14, 2026 · Updated Sep 14, 2026
Out-of-bounds write in Samsung Exynos 1280 Firmware 2025-12-29 and earlier allows attackers to corrupt kernel memory via color-mode data. The DPU driver parses a color-mode lookup table without validating its input length, allowing an out-of-bounds write into kernel memory. The published record does not identify the access level or interface needed to reach the parser; its stated consequence includes potential privilege escalation.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
