Descriptions

Memory leak in the airspy_probe function in drivers/media/usb/airspy/airspy.c in the airspy USB driver in the Linux kernel before 4.7 allows local users to cause a denial of service (memory consumption) via a crafted USB device that emulates many VFL_TYPE_SDR or VFL_TYPE_SUBDEV devices and performs many connect and disconnect operations.

Pérdida de memoria en la función airspy_probe en drivers/media/usb/airspy/airspy.c en el controlador USB airspy en el kernel de Linux en versiones anteriores a 4.7 permite a usuarios locales provocar una denegación de servicio (consumo de memoria) a través de un dispositivo USB manipulado que emula muchos dispositivos VFL_TYPE_SDR o VFL_TYPE_SUBDEV y realiza muchas operaciones de conexión y desconexión.

A missing permission check when settings ACLs was discovered in nfsd. A local user could exploit this flaw to gain access to any file by setting an ACL. Kangjie Lu discovered an information leak in the Reliable Datagram Sockets implementation in the Linux kernel. A local attacker could use this to obtain potentially sensitive information from kernel memory. Various other issues were also addressed.
