CVE-2026-8916

Code execution via truncated outline indexes

Published Jun 4, 2026 · Updated Jun 4, 2026

Out-of-bounds write in Samsung Open Source rlottie before dcfde72eae1b0464dc0dd760aec00ada6a148635 allows attackers to execute code. SW_FT_Outline stores user-controlled point and contour counts as 16-bit shorts, so large outlines truncate indexes before ft_stroke_border_export writes to memory. A consuming application must load crafted Lottie JSON and render it after user interaction; successful exploitation runs code in the current process.
