CVE-2026-97475

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

State: Published
Severity: Not scored

Updated: Oct 3, 2026

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.
