Samsung Seiren Kernel Driver Buffer Overflow

Samsung Seiren Kernel Driver Buffer Overflow
Posted Oct 28, 2015
Authored by Google Security Research, Ian Beer

The Exynos Seiren Audio driver has a device endpoint (/dev/seiren) that is accessible by either the system user or the audio group (such as the mediaserver). It was found that the write() implementation for this driver contains a buffer overflow vulnerability that overflows a static global buffer.
