CVE-2026-63933 Linux CVE debrief

Who should care

Users of Linux kernel versions with the iio: gyro: adis16260 driver should validate and apply patches to prevent potential local denial-of-service attacks. This vulnerability can be exploited by a local attacker to cause a denial-of-service attack. Operators, platform administrators, vulnerability management teams, and security teams should review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.

Technical summary

The Linux kernel's iio: gyro: adis16260 driver has a division by zero vulnerability. When a user writes a zero value to the sampling_frequency sysfs attribute, it triggers a division by zero in the kernel. A validation check has been added for the sampling frequency value before using it as a divisor. This vulnerability can be exploited by a local attacker to cause a denial-of-service attack. Users of Linux kernel versions with the iio: gyro: adis16260 driver should validate and apply patches to prevent potential local denial-of-service attacks. The CVE record was published on 2026-07-19T16:17:11.737Z and has not been modified since then. There is limited information available about the vulnerability, and defenders should verify the affected scope and severity with the vendor.

Defensive priority

Apply patches to address the division by zero vulnerability in the Linux kernel's iio: gyro: adis16260 driver. This vulnerability can be exploited by a local attacker to cause a denial-of-service attack.

Recommended defensive actions

• Validate and apply patches for the Linux kernel's iio: gyro: adis16260 driver
• Monitor sysfs attribute changes for the sampling_frequency value
• Implement compensating controls to limit potential denial-of-service attacks
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
