In the Linux kernel, the following vulnerability has been resolved: spi: Fix simplification of devm_spi_register_controller This reverts commit 59ebbe40fb51 ("spi: simplify devm_spi_register_controller"). If devm_add_action() fails in devm_add_action_or_reset(), devm_spi_unregister() will be called, it decreases the refcount of 'ctlr->dev' to 0, then it will cause uaf in the drivers that calling spi_put_controller() in error path.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: spi: Corrección de la simplificación de devm_spi_register_controller. Esto revierte el commit 59ebbe40fb51 ("spi: simplificar devm_spi_register_controller"). Si devm_add_action() falla en devm_add_action_or_reset(), se llamará a devm_spi_unregister(), lo que reduce el recuento de referencias de 'ctlr->dev' a 0 y, en consecuencia, causará un error uaf en los controladores que llaman a spi_put_controller() en la ruta de error.
