CVE-2026-98666

About vulnerability

In the Linux kernel, the following vulnerability has been resolved:

iio: gyro: adis16136: fix unprotected debugfs reads

The serial_number file operations are open coded and never call debugfs_file_get(), which debugfs_create_file_unsafe() requires. debugfs_remove_recursive() therefore does not wait for a read in progress, and unbind frees the iio_dev underneath it.

Use debugfs_create_file() instead.
