In the Linux kernel, the following vulnerability has been resolved: iio: imu: adis16550: fix stack leak in trigger handler adis16550_trigger_handler() declares the scan data array on the stack without initializing it. The memcpy() at the bottom fills only the first 28 bytes (TEMP + 6 channels of GYRO/ACCEL data), and iio_push_to_buffers_with_timestamp() writes the s64 timestamp at the 8-byte-aligned offset 32. Bytes 28-31 remain uninitialized stack data which leaks to userspace on ever trigger. Fix this all by just zero-initializing the structure on the stack.
