In the Linux kernel, the following vulnerability has been resolved: iio: gyro: adis16260: fix division by zero in write_raw Add a validation check… (CVE-2026-63933)
A vulnerability in the Linux kernel's iio gyro driver for the adis16260 sensor allowed a division by zero error in the write_raw function. This occurred when a user wrote zero to the sampling_frequency sysfs attribute, which was used as a divisor without validation. The issue has been resolved by adding a validation check for the sampling frequency value before use.
AI Analysis
Technical Summary
The Linux kernel's iio gyro adis16260 driver had a vulnerability where writing zero to the sampling_frequency sysfs attribute caused a division by zero in the kernel. This was due to the lack of validation on the sampling frequency value before it was used as a divisor in the write_raw function. The vulnerability has been fixed by introducing a validation check to prevent division by zero.
Potential Impact
A user with the ability to write to the sampling_frequency sysfs attribute could trigger a division by zero in the kernel, potentially causing a kernel crash or denial of service. There is no indication of privilege escalation or code execution from the provided data.
Mitigation Recommendations
The vulnerability has been resolved in the Linux kernel by adding a validation check to prevent division by zero. Users should update to the fixed kernel version once available. Patch status is not yet confirmed in the provided data — check the vendor advisory for current remediation guidance.
