1) Incomplete cleanup (CVE-ID: CVE-2026-98671)
CWE-ID: CWE-459 - Incomplete cleanup
CVSSv4: 2 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a local user to potentially cause a denial of service through incomplete driver cleanup.
The vulnerability exists due to incomplete cleanup in the Linux kernel sun4i-gpadc-iio driver's probe function when thermal zone registration fails with an error other than -ENODEV. A local user can potentially trigger this failure path to leave the IIO map array registered and runtime power management enabled, which may disrupt system operation.
Remediation
Install update from vendor's website.
