CVE-2026-64493

/// Technical description

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

iio: pressure: mpl115: fix runtime PM leak on read error

mpl115_read_raw() takes a runtime PM reference with pm_runtime_get_sync()

before reading the processed pressure or raw temperature, but on the read

error path it returns without calling pm_runtime_put_autosuspend(). Each

failed read therefore leaks a runtime PM reference and prevents the device

from autosuspending.

Drop the reference before checking the return value so both the success

and error paths are balanced.

/// 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.
