Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> iio: backend: fix out-of-bound write<br /> <br /> The buffer is set to 80 character. If a caller write more characters,<br /> count is truncated to the max available space in "simple_write_to_buffer".<br /> But afterwards a string terminator is written to the buffer at offset count<br /> without boundary check. The zero termination is written OUT-OF-BOUND.<br /> <br /> Add a check that the given buffer is smaller then the buffer to prevent.
