Overview

About vulnerability

In the Linux kernel, the following vulnerability has been resolved: smb/server: fix refcount leak in parse_durable_handle_context() When the command is a replay operation and -ENOEXEC is returned, the refcount of ksmbd_file must be released. A reference count leak flaw was found in the Linux kernel’s ksmbd in-kernel SMB server. In the parse_durable_handle_context() function, when a command is detected as a replay operation and returns -ENOEXEC, the reference count of the ksmbd_file structure is not properly released. This leads to a resource leak that could result in gradual memory exhaustion over time.
