DESCRIPTION

* CVE-2016-6828: Use after free during TCP transmission.

A logic error when a memory allocation fails during TCP transmission can
cause the kernel TCP stack to use freed memory causing a kernel panic.


* CVE-2016-6480: Denial-of-service in Adaptec AACRAID driver.

A race condition in fetching parameters from userspace could result in
accessing beyond the bounds of a buffer.  A local user with privileges
to access the device could use this flaw to crash the system.


* CVE-2016-7039: Kernel crash due to unbounded recursion in vlan GRO processing.

Linux kernel built with the 802.1Q/802.1ad VLAN OR Virtual eXtensible LAN
with Transparent Ethernet Bridging(TEB) GRO support, is vulnerable to a stack
overflow issue, leading to a stack corruption in the kernel.

A remote user could use this flaw to cause kernel panic by sending malicious
packets to a server that has GRO enabled.
