AI-suggested
A patch is available and included in multiple Linux kernel versions as part of a broader security update. Users should update their Linux kernel to the patched versions to mitigate this vulnerability. No additional mitigation steps are indicated by the vendor advisory.
Description
A division by zero vulnerability was discovered and fixed in the Linux kernel's iio: gyro: adis16260 driver. The flaw occurred when writing zero to the sampling_frequency sysfs attribute, which could cause a division by zero error. This issue was addressed by adding validation checks on the sampling frequency value before it is used as a divisor. The vulnerability is part of a broader set of Linux kernel security fixes released in multiple kernel versions. Users are advised to update to patched kernel versions to mitigate this vulnerability.
