CVE-2026-8916 · Severity: medium · CVSS 6.1 · Published 2026-06-04

Samsung rlottie is an open-source library used to render vector animations, commonly found in mobile apps and smart devices. A vulnerability in how it handles animation files could allow a specially crafted file to crash an application or cause it to behave unexpectedly. This could lead to service disruptions or stability issues on devices that process these animations.

## Technical details

An out-of-bounds write vulnerability exists in Samsung's rlottie library due to an integer overflow in the SW_FT_Outline point and contour counters. The flaw is triggered when the library processes a maliciously crafted animation file, leading to a buffer overflow. An attacker can exploit this by convincing a user to open a specially crafted file (User Interaction required), potentially resulting in a denial-of-service (application crash) or limited data integrity impact. The issue was addressed in commit dcfde72eae1b0464dc0dd760aec00ada6a148635.
