Summary
In the Linux kernel, the following vulnerability has been resolved: iio: backend: make sure to NULL terminate stack buffer Make sure to NULL terminate the buffer in iio_backend_debugfs_write_reg() before passing it to sscanf(). It is a stack variable so we should not assume it will 0 initialized.
