Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> cifs: Fix memory and information leak in smb3_reconfigure()<br /> <br /> In smb3_reconfigure(), if smb3_sync_session_ctx_passwords() fails, the<br /> function returns immediately without freeing and erasing the newly<br /> allocated new_password and new_password2. This causes both a memory leak<br /> and a potential information leak.<br /> <br /> Fix this by calling kfree_sensitive() on both password buffers before<br /> returning in this error case.
