Descriptions

Multiple buffer overflows in the esa_write function in /dev/seirenin the Exynos Seiren Audio driver, as used in Samsung S6 Edge, allow local users to cause a denial of service (memory corruption) via a large (1) buffer or (2) size parameter.

Múltiples desbordamientos de búfer en la función esa_write en el archivo /dev/seirenin en el controlador Exynos Seiren Audio, como es usado en Samsung S6 Edge, permiten a usuarios locales causar una denegación de servicio (corrupción de memoria) por medio de un parámetro (1) buffer o (2) size de gran tamaño

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.
