Summary
A flaw was found in the Linux kernel that allows the userspace to call memcpy_fromiovecend() and similar functions with a zero offset and buffer length which causes the read beyond the buffer boundaries, in certain cases causing a memory access fault and a system halt by accessing invalid memory address. This issue only affects kernel version 3.10.x as shipped with Red Hat Enterprise Linux 7.

En algunos casos, esto provoca un fallo de acceso a la memoria y la detenci\u00f3n del sistema, accediendo a direcciones de memoria inv\u00e1lidas.
