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.
