Detailsinfo

A vulnerability classified as critical was found in Linux Kernel up to 6.4.10. This vulnerability affects the function device_add. The manipulation with an unknown input leads to a reference count vulnerability. The CWE definition for the vulnerability is CWE-911. The product uses a reference count to manage a resource, but it does not update or incorrectly updates the reference count. As an impact it is known to affect availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: scsi: core: Fix possible memory leak if device_add() fails If device_add() returns error, the name allocated by dev_set_name() needs be freed. As the comment of device_add() says, put_device() should be used to decrease the reference count in the error path. So fix this by calling put_device(), then the name can be freed in kobject_cleanp().

The advisory is available at git.kernel.org. This vulnerability was named CVE-2023-53174 since 09/15/2025. Technical details are known, but there is no available exploit.
