CVE-2026-64497

Published Jul 25, 2026 EPSS 0.18% (7th pctl)

Overview

CVE-2026-64497 is a known-severity vulnerability. It was published on July 25, 2026.

Technical Description

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

iio: chemical: scd30: Cleanup initializations and fix sign-extension bug

Include linux/bitfield.h for FIELD_GET().

Create new macros for bit manipulation in combination with manual bit

manipulation being replaced with FIELD_GET().

The current variable declaration and initializations are barely readable

and use comma separations across multiple lines. Refactor the

initializations so that mantissa and exp have separate declarations and

sign gets initialized later.

In addition (and due to the nature of the cleanup), fix a sign-extension

bug where, float32 would get bitwise anded with ~BIT(31)

(which is 0xFFFFFFFF7FFFFFFF) which corrupted the exponent.

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.
