Rejected after investigation found no security issue
Published Jul 28, 2026 · Updated Jul 28, 2026
ESP32-audioI2S 3.4.5 was assigned CVE-2026-51274 for a reported SYLT parser overflow, but the CNA later rejected the record. The withdrawn report alleged that Audio::read_MP3_Header() trusted an ID3v2 SYLT frame size when allocating and iterating over a lyric buffer. MITRE's rejection states that further investigation found no security issue, so the alleged crash, disclosure, and code-execution impacts are unconfirmed.
