What fixes it

  • 2b498df75d6c29aa3e760127ae0f0003df598b53LinuxCVE List

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

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.
