Doc Text:	A flaw was found in the Linux kernel's `adis16260` gyroscope driver. A local user can trigger a division-by-zero error by writing a zero value to the `sampling_frequency` sysfs attribute. This can lead to a kernel panic, resulting in a system crash and a Denial of Service (DoS).	Story Points:	---

Description OSIDB Bzimport 2026-07-19 16:08:53 UTC

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

iio: gyro: adis16260: fix division by zero in write_raw

Add a validation check for the sampling frequency value before using it
as a divisor. A user writing zero to the sampling_frequency sysfs
attribute triggers a division by zero in the kernel.
