Descriptions

Race condition in net/sctp/socket.c in the Linux kernel before 4.1.2 allows local users to cause a denial of service (list corruption and panic) via a rapid series of system calls related to sockets, as demonstrated by setsockopt calls.

Vulnerabilidad de condición de carrera en net/stcp/socket.c en el kernel de Linux en versiones anteriores a 4.1.2, permite a usuarios locales causar una denegación de servicio (lista corrupta y pánico) a través de una serie de llamadas al sistema relacionadas con sockets, según lo demostrado por las llamadas setsockopt.

A race condition flaw was found in the way the Linux kernel's SCTP implementation handled Address Configuration lists when performing Address Configuration Change (ASCONF). A local attacker could use this flaw to crash the system via a race condition triggered by setting certain ASCONF options on a socket.
