Out-of-bounds write in the BIOS firmware for some Intel(R) Processors may allow an authenticated user to potentially enable escalation of privilege via local access.

A flaw was found in the Linux kernel implementation of userspace core dumps. This flaw allows anyone with access to core dumps to see a small amount of private kernel data about the current running kernels internal state which could be used to further allow an attack to more reliably execute. This information could be user processes or kernel state from previous executions.
