CVE-2016-3951

Vulnerabilidad de liberación de memoria doble en drivers/net/usb/cdc_ncm.c en el kernel de Linux en versiones anteriores a 4.5 permite a atacantes físicamente próximos provocar una denegación de servicio (caída de sistema) o posiblemente tener otro impacto no especificado insertando un dispositivo USB con un descriptor USB no válido.

Justin Yackoski discovered that the Atheros L2 Ethernet Driver in the Linux kernel incorrectly enables scatter/gather I/O. A remote attacker could use this to obtain potentially sensitive information from kernel memory. Jann Horn discovered that eCryptfs improperly attempted to use the mmap() handler of a lower filesystem that did not implement one, causing a recursive page fault to occur. A local unprivileged attacker could use to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges. Various other issues were also addressed.
