CVE-2026-43063

Estado: AnalizadaAlta (7.8)—

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

xfs: don't irele after failing to iget in xfs_attri_recover_work

xlog_recovery_iget* never set @ip to a valid pointer if they return an error, so this irele will walk off a dangling pointer. Fix that.

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.

AV:L + UI:R + acceso local con interacción del usuario (manipulación de archivo XFS) causa crash/DoS por puntero dangling en kernel.

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.
