CVE-2016-8645 Linux kernel vulnerability
Title: Linux kernel vulnerability
Summary: The system could be made to crash under certain conditions.
Marco Grassi discovered that the TCP implementation in the Linux kernel
mishandles socket buffer (skb) truncation. A local attacker could use this
to cause a denial of service (system crash).
Instructions: After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatic
