CVE-2026-98663 PUBLISHED

iio: imu: adis16480: fix unprotected debugfs reads

Assigner: Linux
Reserved: 25.09.2026 Published: 18.10.2026 Updated: 18.10.2026

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

iio: imu: adis16480: fix unprotected debugfs reads

The firmware_revision and firmware_date 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.
