CVE-2026-97475

/// Technical description

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

thermal/drivers/tegra/soctherma: Switch to devm cooling device registration

Use devm_thermal_of_cooling_device_register() to simplify resource

management and avoid manual cleanup in error paths.

As a side effect this change has the benefit of solving an existing

issue. Before, the function tegra_soctherm_remove() only called

debugfs_remove_recursive() and never called thermal_cooling_device_unregister()

for any of the cooling devices registered here.

After the driver removal, the thermal framework's cdev list would

still hold references to thermal_cooling_device objects whose devdata

pointer (ts) pointed to memory already freed by the platform device's

devm cleanup.

With this change, the cooling device is unregistered when the driver

is removed, thus fixing the issue above.

/// 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.
