Assigner: kernel.org

Description
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.

Executive Summary

This vulnerability is a division by zero issue in the Linux kernel's IIO gyro driver for the ADIS16260 sensor. It occurs when a user writes a zero value to the sampling_frequency sysfs attribute, causing the kernel to attempt dividing by zero during processing.

Detection Guidance

This vulnerability can be detected by checking for attempts to write zero to the sampling_frequency sysfs attribute of the adis16260 gyro driver. Monitor kernel logs for division by zero errors related to this driver.

Impact Analysis

This vulnerability could cause a kernel crash or system instability if exploited. An attacker with local access could trigger a denial of service by writing zero to the sampling_frequency attribute.

Compliance Impact

This vulnerability does not directly affect compliance with GDPR, HIPAA, or similar standards. It is a local denial-of-service issue in the Linux kernel's IIO gyro subsystem, caused by a division by zero when writing zero to a sysfs attribute. No data exposure or privacy impact is described.

Mitigation Strategies

Apply the Linux kernel patch that adds validation for the sampling_frequency value. Ensure the adis16260 driver is updated to prevent division by zero when zero is written to sampling_frequency.
