SYNTHESIS OF THE VULNERABILITY
An attacker can change the page zero on the Linux kernel, in order
to trigger a denial of service, and possibly to run code.
– Impacted products: Linux, openSUSE.
– Severity: 2/4.
– Creation date: 25/08/2016.
DESCRIPTION OF THE VULNERABILITY
The memory page at address zero is reserved.
However, in some cases, a local attacker can write data at this
address.
An attacker can therefore change the page zero on the Linux
kernel, in order to trigger a denial of service, and possibly to
run code.
