Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A vulnerability in the Linux kernel has been resolved, related to the simplification of devm spi register controller. The issue arises when devm add action() fails in devm add action or reset(), leading to devm spi unregister() being called, which decreases the refcount of 'ctlr->dev' to 0. This causes a use-after-free (uaf) in drivers that call spi put controller() in the error path.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
