CVE-2026-80565

Estado: RecibidaAlta (7.8)—

In the Linux kernel, the following vulnerability has been resolved:

crypto: qce - fix error path in devm_qce_register_algs

If ops->register_algs() fails, the error path repeatedly calls the same ops->unregister_algs() from the failed registration. Use the loop index to unregister the previously registered algorithms instead.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 7.8

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.18%
Percentil entre todas las CVEs puntuadas: 6
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.

ExplotaciónT1068 Exploitation for Privilege Escalationprivilege escalation85 %
Impacto principalT1059 Command and Scripting Interpreterexecution75 %

Acceso local sin interacción (AV:L/UI:N/PR:L) permite escalada de privilegios (C:H/I:H/A:H); fallo en manejo de errores en registro de algoritmos criptográficos puede derivar en ejecución de código.
