Descriptions

The rfcomm_sock_bind function in net/bluetooth/rfcomm/sock.c in the Linux kernel before 4.2 allows local users to obtain sensitive information or cause a denial of service (NULL pointer dereference) via vectors involving a bind system call on a Bluetooth RFCOMM socket.

La función rfcomm_sock_bind en net/bluetooth/rfcomm/sock.c en el kernel de Linux en versiones anteriores a 4.2 permite a usuarios locales obtener información sensible o provocar una denegación de servicio (referencia a puntero NULL) a través de vectores relacionados con una llamada de sistema enlazada en un enchufe Bluetooth RFCOMM.

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix: It was found that the Linux kernel's IPv6 implementation mishandled socket options. A local attacker could abuse concurrent access to the socket options to escalate their privileges, or cause a denial of service via a crafted sendmsg system call.
