Vigil@nce - Linux kernel: buffer overflow of videobuf2-v4l2
July 2016 by Vigil@nce
This bulletin was written by Vigil@nce : https://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
An attacker can generate a buffer overflow in videobuf2-v4l2 of
the Linux kernel, in order to trigger a denial of service, and
possibly to run code.
Impacted products: Linux.
Severity: 2/4.
Creation date: 09/05/2016.
DESCRIPTION OF THE VULNERABILITY
The Linux kernel uses a buffer for video.
However, if the size of data is greater than the size of the
storage array, an overflow occurs.
An attacker can therefore generate a buffer overflow in
videobuf2-v4l2 of the Linux kernel, in order to trigger a denial
of service, and possibly to run code.
