CVE-2026-89934 is a known-severity vulnerability. It was published on September 16, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
iio: light: ltrf216a: fix runtime PM reference leak in error path
ltrf216a_get_lux() acquires a runtime PM reference by calling
ltrf216a_set_power_state(data, true). However, if
ltrf216a_read_data() fails, the function returns immediately without
dropping the reference.
This leaves the runtime PM usage count unbalanced, preventing the device
from autosuspending after a failed read.
Fix this by releasing the runtime PM reference before returning from the
error path.
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.
