CVE-2026-63966CVE-2026-63966
Description
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.
