Descriptions

In the Linux kernel, the following vulnerability has been resolved:

i2c: i801: Fix block process call transactions

According to the Intel datasheets, software must reset the block
buffer index twice for block process call transactions: once before
writing the outgoing data to the buffer, and once again before
reading the incoming data from the buffer.

The driver is currently missing the second reset, causing the wrong
portion of the block buffer to be read.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: i2c: i801: Reparar transacciones de llamada de proceso de bloque Según las hojas de datos de Intel, el software debe restablecer el índice del búfer de bloque dos veces para transacciones de llamada de proceso de bloque: una vez antes de escribir los datos salientes en el búfer , y una vez más antes de leer los datos entrantes del búfer. Actualmente, al controlador le falta el segundo reinicio, lo que provoca que se lea la parte incorrecta del búfer de bloque.
