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

Description: The issue is related to a reference count leak in the uniphier spi probe() function. This occurs when either dma get slave caps() or devm spi register master() returns an error code, causing the function to forget to decrease the refcount of both dma rx and dma tx objects. This may lead to refcount leaks. The issue happens in several error paths in uniphier spi probe().

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