CVE-2026-2588

Estado: AnalizadaCrítica (9.1)—

Crypt::NaCl::Sodium versions through 2.001 for Perl has an integer overflow flaw on 32-bit systems.

Sodium.xs casts a STRLEN (size_t) to unsigned long long when passing a length pointer to libsodium functions. On 32-bit systems size_t is typically 32-bits while an unsigned long long is at least 64-bits.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vector CVSS N/N/L indica explotación remota sin autenticación (T1190). Integer overflow en casting de size_t puede permitir ejecución de código arbitrario (T1059) o DoS (T1499.004) al desbordar buffers en libsodium.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
