Description
This security bulletin contains information about 1 vulnerability.
1) Integer overflow (CVE-ID: CVE-2026-64497)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a local user to cause incorrect sensor data processing.
The vulnerability exists due to an integer sign-extension bug in the scd30_float_to_fp() function in the SCD30 IIO chemical sensor driver when converting floating-point sensor values. A local user can trigger the conversion of a crafted floating-point value to cause incorrect sensor data processing.
The issue affects the Linux kernel SCD30 sensor driver code path that converts device-provided floating-point values into fixed-point representation.
Remediation
Install update from vendor's website.
