Published Aug 15, 2026 EPSS 0.17% (7th pctl)

Overview

CVE-2026-74546 is a known-severity vulnerability. It was published on August 15, 2026.

Technical Description

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

hwmon: (adt7470) Fix divide-by-zero TOCTOU crash in fan speed read

If the fan data becomes 0 between the FAN_DATA_VALID() check and the

FAN_PERIOD_TO_RPM() conversion, it will result in a divide-by-zero crash

due to a race with a concurrent update of the cached fan value.

Fix a TOCTOU issue by reading fan data once.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
