CVE-2026-46291
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
crypto: caam - guard HMAC key hex dumps in hash_digest_key
Use print_hex_dump_devel() for dumping sensitive HMAC key bytes in hash_digest_key() to avoid leaking secrets at runtime when CONFIG_DYNAMIC_DEBUG is enabled.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
- Puntuación base: 5.5
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.16%
- Percentil entre todas las CVEs puntuadas: 5
- 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).
