CVE-2026-43598

Estado: Pendiente de análisisAlta (7.7)—

Improper input validation in the AMD ROCm Communication Collectives Library (RCCL) could allow a compromised peer rank or network-adjacent attacker to dereference an attacker-controlled pointer, potentially resulting in remote code execution.

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.

Vulnerabilidad de validación de entrada en biblioteca remota (RCCL) con PR:L y AV:N; ataque desde par comprometido o adyacente permite desreferenciación de puntero controlado. Explotación de servicio remoto (T1210). Impactos: ejecución de código arbitrario (T1059) y potencial DoS por corrupción de m
