CVE-2026-54073

VeraCrypt provides disk encryption with strong security based on TrueCrypt. From 1.26.6 until 1.26.29, file-hosted hidden volume creation forces quick format and the FormatNoFs function in src/Common/Format.c and FormatFat function in src/Common/Fat.c use WriteFile to place raw zeroed sectors at predictable 128 MiB intervals. These writes bypass the normal EncryptDataUnits formatting path, leaving deterministic plaintext markers in an area expected to resemble random ciphertext. The markers can weaken plausible deniability during forensic inspection, although they do not disclose hidden-volume content or reduce the strength of VeraCrypt encryption. This issue is fixed in version 1.26.29.

Summary		(es) VeraCrypt proporciona cifrado de disco con seguridad robusta basado en TrueCrypt. Desde la versión 1.26.6 hasta la 1.26.29, la creación de volúmenes ocultos alojados en archivos fuerza el formato rápido y la función FormatNoFs en src/Common/Format.c y la función FormatFat en src/Common/Fat.c usan WriteFile para colocar sectores en bruto rellenados con ceros en intervalos predecibles de 128 MiB. Estas escrituras eluden la ruta de formato normal de EncryptDataUnits, dejando marcadores de texto plano deterministas en un área que se espera que se asemeje a un texto cifrado aleatorio. Los marcadores pueden debilitar la negación plausible durante una inspección forense, aunque no revelan el contenido del volumen oculto ni reducen la fuerza del cifrado de VeraCrypt. Este problema está solucionado en la versión 1.26.29.
