Overview

About vulnerability

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

spi: meson-spicc: Fix double-put in remove path

meson_spicc_probe() registers the controller with devm_spi_register_controller(), so teardown already drops the controller reference via devm cleanup.

Calling spi_controller_put() again in meson_spicc_remove() causes a double-put.
