Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The vulnerability is related to a resource leak in the Linux kernel's SDIO component. When
sdio add func() or sdio init func() fails, sdio remove func() cannot release the resources because the SDIO function is not presented in these cases, resulting in a potential leak. The issue is fixed by making sdio func present() control whether device del() needs to be called or not and always calling of node put() and put device(). In error cases in sdio init func(), moving get device() to sdio alloc func() and put device() to sdio release func() keeps the get/put function balanced.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
