How the CVE Works
CVE-2025-53076 is an Improper Input Validation vulnerability in Samsungβs open-source rLottie library (v0.2). The flaw occurs when processing malformed animation files, leading to buffer overreads. Attackers can craft a specially designed input that bypasses validation checks, causing the library to read beyond allocated memory boundaries. This could result in crashes or potential information leaks, though remote code execution is unlikely due to memory protections. The vulnerability is network-exploitable (AV:N) but requires user interaction (UI:A).
