An out-of-bounds write vulnerability was found in the Linux kernel’s
SLIMpro I2C device driver. The userspace “data->block[0]” variable was not
capped to a number between 0-255 and was used as the size of a memcpy,
possibly writing beyond the end of dma_buffer. This flaw could allow a
local privileged user to crash the system or potentially achieve code
execution.
