CVE-2026-71694
An issue in Berkeley Out-of-Order Machine (BOOM) / BoomTile RTL benchmark v1.2 2d08d0d8b4563212175212f9db0e69f6e68c9619 allows a remote attacker to execute arbitrary code via the CSR trap-return state restoration logic, MRET handling logic, mstatus.MPRV update path, CSRFile logic in ProcessorFuzz BOOM benchmark Benchmarks/Verilog/SmallBoomTile_v1.2_state.v
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
- Puntuación base: 8.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.38%
- Percentil entre todas las CVEs puntuadas: 30
- Fecha de la puntuación: 6/10/2026
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.
- Explotación
T1203Exploitation for Client Executionexecution75 % - Impacto principal
T1059Command and Scripting Interpreterexecution70 % - Impacto secundario
T1548.004Elevated Execution with Promptprivilege escalation65 %
UI:R + AV:N indica ejecución en cliente con interacción del usuario (T1203). El fallo en lógica de RTL/CSR permite ejecutar código arbitrario (T1059) y potencialmente elevar privilegios mediante manipulación de MRET/mstatus (T1548.004).
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.
