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

Description The vulnerability is related to the hisi sas component in the Linux kernel. It occurs when the init debugfs fails during device registration due to memory allocation failure, causing debugfs remove recursive() to be called without setting debugfs dir to NULL. As a result, debugfs remove recursive() is called again during device removal, leading to an illegal pointer access. This can cause a kernel NULL pointer dereference, resulting in a denial of service.

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