CVE-2025-0647
Estado: AnalizadaAlta (7.9)—
In certain Arm CPUs, a CPP RCTX instruction executed on one Processing Element (PE) may inhibit TLB invalidation when a TLBI is issued to the PE, either by the same PE or another PE in the shareability domain. In this case, the PE may retain stale TLB entries which should have been invalidated by the TLBI.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N
- Puntuación base: 7.9
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.17%
- Percentil entre todas las CVEs puntuadas: 6
- Fecha de la puntuación: 5/10/2026
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).

Vulnerabilidad de firmaware Arm en instrucción CPP RCTX que impide invalidación de TLB. Acceso local (AV:L) con privilegios altos (PR:H) sin interacción explica T1068. Retención de entradas TLB stale permite escalada de privilegios (T1548.004) o DoS (T1499.004) al mantener mapeos de memoria obsoleto
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.
