Description

A flaw was found in ksmbd, a Linux kernel module that provides an in-kernel SMB server. A race condition exists in the session lookup and expiration process. This issue occurs because the session reference count is not properly incremented within the lock during lookup. A remote attacker could potentially exploit this to cause a denial of service due to improper session handling.
