CVE-2026-92504

Estado: RecibidaAlta (7)—

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

thermal: intel: int3400: clean up ODVP on probe failures

evaluate_odvp() creates per-ODVP sysfs files before the thermal zone and later probe resources are registered. The current unwind path only calls cleanup_odvp() from the late sysfs failure path, so failures after evaluate_odvp() but before that label, including thermal_tripless_zone_device_register() failures, leave the ODVP files and storage behind.

Move the ODVP cleanup to the common ART/TRT unwind path so every failure after evaluate_odvp() releases the ODVP state. Also clear the cached ODVP pointers in cleanup_odvp(), because evaluate_odvp() can already call it for partial setup failures while probe continues.

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 local (AV:L, PR:L) en kernel Linux por manejo deficiente de recursos; potencial DoS por fugas de memoria en sysfs. Sin detalles de explotación activa documentada.

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.
