CVE-2011-1044

Estado: ModificadaBaja (2.1)—

La función ib_uverbs_poll_cq en drivers/InfiniBand/core/uverbs_cmd.c en el kernel de Linux antes de v2.6.37 no inicializa determinado buffer de respuesta, lo que permite obtener información sensible de la memoria del kernel a usuarios locales a través de vectores que causan que este búfer este sólo parcialmente lleno. Se trata de una vulnerabilidad diferente a CVE-2010-4.649.

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).
