Descriptions

In the Linux kernel before 4.1.4, a buffer overflow occurs when checking userspace params in drivers/media/dvb-frontends/cx24116.c. The maximum size for a DiSEqC command is 6, according to the userspace API. However, the code allows larger values such as 23.

En el kernel de Linux anterior a versión 4.1.4, ocurre un desbordamiento de búfer cuando se comprueban los parámetros username en el archivo drivers/media/dvb-frontends/cx24116.c. El tamaño máximo para un comando DiSEqC es 6, según la API de username. Sin embargo, el código permite valores más grandes como 23.

A vulnerability was found in the Linux kernel’s CX24116 tv-card driver, where an out of bounds read occurs when checking userspace params in drivers/media/dvb-frontends/cx24116.c. An attacker could use this flaw to leak kernel private information to userspace.
