CVE-2026-87961

HighCVSS 7.1
Published: Updated: Translated: NVD NIST

Summary

ESP32-audioI2S versions 3.4.4 through 4.0.0 contain a heap-based out-of-bounds read vulnerability in the read_ID3_Header function due to a shadowed length parameter in ID3 synchronized-lyrics processing. Attackers can craft malicious MP3 files or HTTP audio streams with oversized frame size declarations to read past allocated buffer boundaries.

Risk Assessment

This can cause device crashes or expose adjacent heap memory, posing a risk of data leakage or device instability.

Recommendation

Update ESP32-audioI2S to a version newer than 4.0.0 if available, and avoid playing untrusted MP3 files or audio streams.
