Vigil@nce - Linux kernel: denial of service via S/390 Linkage Stack
February 2014 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
A local attacker can use the S/390 Linkage Stack, in order to
trigger a denial of service of the Linux kernel.
Impacted products: Linux
Severity: 1/4
Creation date: 21/02/2014
DESCRIPTION OF THE VULNERABILITY
The Linux kernel can be installed on S/390 processors.
The Linkage Stack is a shared memory area where processes can
store information during a state change.
However, if the process uses a low memory address, the kernel
panics.
A local attacker can therefore use the S/390 Linkage Stack, in
order to trigger a denial of service of the Linux kernel.
