This vulnerability allows remote malicious users to disclose sensitive information on affected installations of Linux Kernel. Authentication is not required to exploit this vulnerability, but only systems with ksmbd enabled are vulnerable. The specific flaw exists within the processing of SMB2_QUERY_INFO and SMB2_LOGOFF commands. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the kernel.
