CVE-2026-93142

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

thermal/drivers/rcar: Fix error checking in probe()

This code accidentally calls thermal_zone_device_enable() before checking

whether thermal_zone_device_register_with_trips() failed. Move the call

until later to avoid an error pointer dereference of "priv->zone".

The driver works differently depending on if we are using OF thermal or

not. We use thermal_add_hwmon_sysfs() if we are using OF thermal and

call thermal_zone_device_enable() if not. We can share same error check

for if either of these fail.

Moving the thermal_zone_device_enable() call is a bit cleaner as well.

The original code used a three step process to cleanup:

1. Call thermal_zone_device_unregister() to cleanup.

2. Set priv->zone to an error pointer to preserve the error code.

3. Set priv->zone to NULL to avoid a second call to

thermal_zone_device_unregister() in the rcar_thermal_remove()

function.

Now we can just do a direct goto error_unregister and rcar_thermal_remove()

handles the cleanup properly.
