CVE detail

CVE-2026-51274

In schreibfaul1 ESP32-audioI2S 3.4.5, a heap-based buffer overflow in the ID3v2 SYLT synchronized lyrics parser in audiolib allows remote attackers to cause a denial of service (application crash), information disclosure, or potential arbitrary code execution via a crafted MP3 file. The vulnerability occurs due to missing bounds validation on attacker-controlled frame size and improper memory access during lyric parsing.
