Details

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.

Severity ?
