Published Jul 28, 2026 · Updated Jul 28, 2026
CVE-2026-51252 was withdrawn by its CNA after further investigation determined that the reported ESP32-audioI2S flaw was not a security issue. The rejection removed the original buffer-overflow description, CWE mapping, CVSS and SSVC assessments, references, and affected-product assertion from the active record. No confirmed vulnerability mechanism, affected version, exploit impact, or exposure gate remains for enterprise triage.
