Descriptions
illumos, as used in OmniOS Community Edition before r151030y, allows a kernel crash via an application with multiple threads calling sendmsg concurrently over a single socket, because uts/common/inet/ip/ip_attr.c mishandles conn_ixa dereferences.
illumos, como es usado en OmniOS Community Edition versiones anteriores a r151030y, permite un bloqueo del kernel por medio de una aplicación con múltiples hilos (subprocesos) que llaman a sendmsg simultáneamente en un solo socket, porque el archivo uts/common/inet/ip/ip_attr.c maneja inapropiadamente las desreferencias de conn_ixa.
