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.
