A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 17.10
The system could be made to crash under certain conditions.
- linux: Linux kernel
- linux-raspi2: Linux kernel for Raspberry Pi 2
It was discovered that the Broadcom UniMAC MDIO bus controller driver in
the Linux kernel did not properly validate device resources. A local
attacker could use this to cause a denial of service (system crash).
The problem can be corrected by updating your system to the following
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 automatically perform
this as well.
