Descriptions
net/sctp/sm_sideeffect.c in the Linux kernel before 4.3 does not properly manage the relationship between a lock and a socket, which allows local users to cause a denial of service (deadlock) via a crafted sctp_accept call.
net/sctp/sm_sideeffect.c en el kernel de Linux en versiones anteriores a 4.3 no maneja adecuadamente la relación entre un bloqueo y un socket, lo que permite a usuarios locales provocar una denegación de servicio (interbloqueo) a través de una llamada sctp_accept manipulada.
A race condition flaw was found in the way the Linux kernel's SCTP implementation handled sctp_accept() during the processing of heartbeat timeout events. A remote attacker could use this flaw to prevent further connections to be accepted by the SCTP server running on the system, resulting in a denial of service.
